Final answer:
Bella spends $15.375 on 3 pounds of blueberries and 1.5 pounds of raspberries. For variable quantities, the cost is $3.75xx for blueberries and $2.75yy for raspberries, where xx and yy are the amounts of blueberries and raspberries in pounds.
Step-by-step explanation:
To calculate how much Bella spends on blueberries and raspberries, we can perform a simple multiplication for each item and then add the totals together.
First scenario: 3 pounds of blueberries at $3.75 per pound and 1.5 pounds of raspberries at $2.75 per pound.
Cost of blueberries = 3 pounds × $3.75/pound = $11.25
Cost of raspberries = 1.5 pounds × $2.75/pound = $4.125
Total cost = $11.25 + $4.125 = $15.375 (or $15.38 rounded to the nearest cent)
Second scenario: xx pounds of blueberries and yy pounds of raspberries.
Cost of blueberries = xx pounds × $3.75/pound = $3.75xx
Cost of raspberries = yy pounds × $2.75/pound = $2.75yy
Total cost = $3.75xx + $2.75yy
