Final answer:
To determine the cost of 5 yards of fabric, divide the total cost for 3 yards by 3 to get the price per yard, then multiply by 5. The 5 yards would cost $30.85, and no further rounding is needed.
Step-by-step explanation:
If you paid $18.50 for 3 yards of fabric, the cost per yard is found by dividing the total cost by the number of yards. So, $18.50 ÷ 3 yards equals approximately $6.17 per yard. To find out how much 5 yards would cost, you multiply the cost per yard by 5:
$6.17 per yard × 5 yards = $30.85
Therefore, the cost for 5 yards of fabric would be $30.85. However, you have also been asked to round to the nearest cent. Since the calculation results in a whole number of cents, no further rounding is necessary, and your final answer remains $30.85.
