Praxis 5003 Practice Question
The cost of 3 identical cans of peaches at a store is $2.67. At this rate, what is the cost of 8 cans of peaches?
Correct Answer: B
Rationale: To determine the cost of 8 cans of peaches, first calculate the cost per can. The total cost for 3 cans is $2.67, so the cost per can is $2.67 ÷ 3 = $0.89. Next, multiply the cost per can by the number of cans desired: $0.89 × 8 = $7.12.
Option A ($5.34) incorrectly assumes a lower cost per can or miscalculates the total for 8 cans. Option C ($8.01) overestimates the total by miscalculating the multiplication. Option D ($21.36) suggests an inflated total, possibly based on a misunderstanding of the multiplication process.
