Answer:
x <= 13
maximum 13 or less than 13 copies can be made
Explanation:
amount you have to make copies $5.25
let x be the number of copies we can make from $5.25
1 copy costs $.40
x copies cost 5.25/.40
x = 13
thus, the number of copies which can be made from $5.25 is maximum 13 or less than 13,
x <= 13
