13. Company C produces toy trucks at a cost of $5.00
    each for the first 100 trucks and $3.50 for each
    additional truck. If 500 toy trucks were produced
    by Company C and sold for $10.00 each, what was
    Company C's gross profit?

(A) $2,250

(B) $2,500

(C) $3,100

(D) $3,250

(E) $3,500

Arithmetic Applied roblems

The company's gross profit on the 500 toy trucks is

the company's revenue from selling the trucks minus

the company's cost of producing the trucks. The

revenue is (500)($10.00) = $5,000. The cost for the

first 100 trucks is (100)($5.00) = $500, and the cost

for the other 400 trucks is ( 400)($3.50) = $1,400

for a total cost of $500 + $1,400 = $1,900. Thus, the

company's gross profit is $5,000 - $1,900 = $3,100.

The correct answer is C.

14. A group of store managers must assemble
    280 displays for an upcoming sale. If they assemble
    25 percent of the displays during the first hour and
    40 percent of the remaining displays during the second
    hour, how many of the displays will not have been
    assembled by the end of the second hour?

(A) 70

(B) 98

(C) 126

(D) 168

(E) 182

Arithmetic ere ntc

If, during the first hour, 25 percent of the total

displays were assembled, then 280(0.25) =

70 displays were assembled, leaving 280 - 70 =

210 displays remaining to be assembled. Since

40 percent of the remaining displays were

assembled during the second hour, 0.40(210) =

84 displays were assembled during the

second hour. Thus, 70 + 84 = 154 displays

were assembled during the first two hours and

280 - 154 = 126 displays had not been assembled

by the end of the second hour.

The correct answer is C.
