Final answer:
To find the cost of 7 cans of fruit cocktails, you first determine the price per can at $2.50 by dividing the cost for 4 cans ($10) by 4. Multiplying the price per can by 7 gives the total cost, which is $17.50.
Step-by-step explanation:
To find the price of 7 cans of fruit cocktails when 4 cans are sold for $10, we need to calculate the price per can and then multiply by the desired number of cans.
Step-by-step calculation:
- First, determine the price per can by dividing the total price by the number of cans: 4 cans for $10 results in $10 ÷ 4 = $2.50 per can.
- Next, multiply the price per can by the number of cans desired: 7 cans × $2.50 per can = $17.50.
Therefore, 7 cans of fruit cocktails will cost $17.50.
