**Answer:**

$12

**Step-by-step explanation:**

Lola has x.

Mary-Ann has 2 1/3 times Lola's amount, so Mary-Ann has (2 1/3)x.

Mary-Ann has $28.

(2 1/3)x = 28

7/3 x = 28

Multiply both sides by 3/7.

x = 28 * 3/7

x = 12

Lola has $12.

A function intercepts the y line, when x is equal to 0. So we insert x=0 and get:
