Answer:7 ounces
Step-by-step explanation:
If they charge 0.50 cents per ounce then u would take the 50 cents and add that up until it gets to 3.50 and that will give u 7 so the answer is 7 ounces.
4(x-2/3) = -18
4x - 8/3 = -18
4x = -54/3 + 8/3
4x = -46/3
x = -46/3 * 1/4
x = -46/12
x = -23/2
2x = -23/2 * 2
2x = -46/2
2x = -23
