Hello there. To solve this question, we'll have to multiply the number of pounds by the cost for each type of berries in order to find the combined cost.
Knowing a pound of strawberries costs $3.45 and a pound of blueberries costs $5.98, we want to find the combined cost of 0.8 and 1.5 pounds of strawberries and blueberries, respectively.
In this case, we just need to evaluate:
Number of pounds of strawberries * cost for a pound + Number of pounds of blueberries * cost for a pound
Namely
0.8 * 3.45 + 1.5 * 5.98
Multiplying the numbers
2.76 + 8.97
Add the numbers
$11.73
This is the combined price of the berries we've been looking for.
