#### In a certain brick wall, each row of bricks above the bottom row contains one less brick than the row just below it. If there are 5 rows in all and a total of 75 bricks in the wall, how many bricks does the bottom row contain ?

Let number of bricks in the bottom row =x Total number of bricks = 75 Total number of rows = 5 x+ x-1 + x-2 + x -3 + x-4 = 75 => 5x = 85 => x= 17 Number of bricks in the bottom row = 17 Answer D

#### A technician makes a round-trip to and from a certain service center by the same route. If the technician completes the drive to the center and then completes 10 percent of the drive from the center, what percent of the round-trip has the technician completed?

" If the technician completes the drive to the center " it actually means completed 50% of the entire trip then 10% of this more so overall 55%

#### A certain manufacturer produces items for which the production costs consist of annual fixed costs totaling $130,000 and variable costs averaging $8 per item. If the manufacturer's selling price per item is $15, how many items must the manufacturer produce and sell to earn an annual profit of $150,000 ?

Profit = Revenue - Cost. Let x is the number of items the manufacturer must produce and sell. Profit = 150,000; Revenue = 15x; Cost = 130,000 + 8x. 150,000 = 15x - (130,000 + 8x); 280,000 = 7x; x = 40,000. Answer: E.

#### Lois has x dollars more than Jim has, and together they have a total of y dollars. Which of the following represents the number of dollars that Jim has?

Let J be the number of dollars that Jim has. Then Lois has J+x dollars. Since together they have a total of y dollars, then J+(J+x)=y --> J=(y-x)/2. Answer: A. ======================================================== 1) Set up the equations: [L = J + x], [L + J = y] 2) Substitute L for J + x and insert this in the second equation, solve so you only have J separately on one side ----> J = (y - x)/2

#### Of the following, which is the closest to (60.2)/(1.03âˆ—4.86) ?

60.2 is nearest to 60 1.03 is nearest to 1 4.86 is nearest to 5 60/1*5 =12 Thus the best answer is B.

#### 2x+2y=âˆ’42x+2y=âˆ’4 4x+y=14x+y=1 In the system of equations above, what is the value of x ?

Reduce the first equation by 2 and subtract it from the second one: (4x+y)âˆ’(x+y)=1âˆ’(âˆ’2)(4x+y)âˆ’(x+y)=1âˆ’(âˆ’2) --> 3x=33x=3 --> x=1x=1.
