GRE Quantitative Reasoning QUESTION #8180

Question 1

A fabric store sells material at \$8.00 per yard, but only in whole-yard increments. Each of 3 curtains requires 1.6 yards of fabric, and all the fabric is bought as one continuous piece. What is the total purchase cost?

$\$40.00$✔️
$\$38.40$
$\$24.00$
$\$16.00$

Correct Answer Explanation

Total fabric needed: $3 \times 1.6 = 4.8$ yards.

Since fabric is sold only in whole-yard increments, you must purchase $5$ full yards (round up from 4.8).

Total cost $= 5 \times \$8.00 = \mathbf{\$40.00}$.
