Answer:
20p = x
Explanation:
Since Lily sold 5 purses in week one and 15 purses in week two that adds up to be a total of 20 purses sold in two weeks. Since p represents the profit for each purse she can use the expression below which simply multiplies the profit per purse (p) by the total amount of purses sold in the two weeks which would give her the total amount of profit (x) that she made from all of her sales.
20p = x
