Question

how many walnuts does Julian need to make in order to break even.

Answer 1

the expression of the income is,

y = 16x - 130

the expression for cost or manufacturing cost is,

y = 8x + 150

for break-even order

it means no profit or no losss

so the total cost of wallets will equal to total income,

16x - 130 = 8x + 150

16x - 8x = 150 + 130

8x = 280

x = 280/8

x = 35

so the number of wallets order is 35 for break-even.
