1 answer

Let x be the number of phone cases sold.

The total cost to make x phone cases is 0.60x dollars.

The price for each phone case is $25.

Therefore, the total earnings from selling x phone cases is equal to the total revenue minus the total cost:

Total earnings = Total revenue - Total cost

Total earnings = 25x - 0.60x

Total earnings = 24.40x

Thus, the equation that represents my total earnings based on the price of the phone cases and the number sold is:

E(x) = 24.40x.

Where E(x) is the total earnings and x is the number of phone cases sold.
