Answer:
The cost of x small boxes and y large boxes is $2.50x + $4.20y.
Explanation:
o get 3 small boxes and 8 large boxes, we can calculate the total cost as follows:
Cost of 3 small boxes = 3 x $2.50 = $7.50
Cost of 8 large boxes = 8 x $4.20 = $33.60
Total cost = $7.50 + $33.60 = $41.10
To find the cost for x small boxes and y large boxes, we can use the following equation:
Total cost = (cost of x small boxes) + (cost of y large boxes)
Substituting the given prices, we get:
Total cost = ($2.50 x) + ($4.20 y)
Therefore, the cost of x small boxes and y large boxes is $2.50x + $4.20y.
