Company Q plans to make a new product next year and sell each unit of this new product at a selling price of $2. The variable costs per unit in each production run are estimated to be 40% of the selling price, and the fixed costs for each production run are estimated to be $5,040. Based on these estimated costs, how many units of the new product will Company Q need to make and sell in order for their revenue to equal their total costs for each production run?

Correct! Wrong!

Explanation The variable costs per unit = 0.4*2 = $0.8. So, we are left with $1.2. To break even with $5,040 of fixed costs, $5,040/1.2 = $5,040*5/6 = 4,200 units should be made. Answer: A.

In the rectangular coordinate system above, if point R (not shown) lies on the positive y-axis and the area of triangle ORP is 12, what is the y-coordinate of point R?

Correct! Wrong!

In the figure above, if PQRS is a parallelogram, then y - x =

Correct! Wrong!

In parallelogram corresponding angles are equal and consecutive angles are supplementary (supplementary angles are two angles that add up to 180°), thus: 140=2y140=2y --> y=70y=70; 2y+x=1802y+x=180 --> 140+x=180140+x=180 --> x=40x=40; Therefore, y−x=70−40=30y−x=70−40=30. Answer: A.

A certain pair of used shoes can be repaired for $12.50 and will last for 1 year. A pair of the same kind of shoes can be purchased new for $28.00 and will last for 2 years. The average cost per year of the new shoes is what percent greater than the cost of repairing the used shoes?

Correct! Wrong!

28 / 2 = 14 14 - 12.50 = 1.50 1.50 / 12.50 = .12 = 12% Answer choice C

If a = 105 and a^3 = 21 × 25 × 45 × b, what is the value of b?

Correct! Wrong!

Explanation This question calls for some prime factorization a = 105 = (3)(5)(7) So, a³ = [(3)(5)(7)]³ = (3)(3)(3)(5)(5)(5)(7)(7)(7) We're told that a³ = 21 × 25 × 45 × b Take: a³ = (3)(3)(3)(5)(5)(5)(7)(7)(7) Rewrite as: a³ = (3)(3)(3)(5)(5)(5)(7)(7)(7) = (3)(3)(21)(5)(5)(5)(7)(7) Now rewrite as: a³ = (3)(3)(21)(5)(5)(5)(7)(7) = (3)(3)(21)(25)(5)(7)(7) Now rewrite as: a³ = (3)(3)(21)(25)(9)(7)(7) = (21)(25)(45)(7)(7) If 21 × 25 × 45 × b = (21)(25)(45)(7)(7), then b = (7)(7) = 49

The sum of three integers is 40. The largest integer is 3 times the middle integer, and the smallest integer is 23 less than the largest integer. What is the product of the three integers?

In the rectangular coordinate system above, if point R (not shown) lies on the positive y-axis and the area of triangle ORP is 12, what is the y-coordinate of point R?

Correct! Wrong!

The area of triangle OPR is 1/2*base*height=1/2*OP*OR=1/2*4*OR=12 --> OR=6.

What is the combined area, in square inches, of the front and back of a rectangular sheet of paper measuring 8.5 inches by 11 inches?

Correct! Wrong!

Explanation Im not sure what does front and back area means, do we have to multiply by 2. front side area of rectangle : 11*8.5: 93.5 in2 back side area of rectangle : 93.5+93.5: 187 in2 option E ================================================================= Area of a rectangle = l x b = 11 x 8.5 = 93.5 Front and Back side = 93.5+93.5 = 187 the answer is E. =================================================================== Area = (base)(height) We want the combined area of BOTH sides (front and back) So, the combined area = (8.5)(11) + (8.5)(11) = (17)(11) = 187 Answer: E
