Gabriel Jacobson · Answer 1

Let's call iggy "i".

5 * i - 8 < = 72 / / add 8 to both sides

5 * i < = 80 / / divide by 5. Since 5 is positive, we do not flip the inequality.

i < = 16

Iggy has 16 or less marbles.

Malachi Meza · Answer 2

N = the number of marbles that iggy has

5n - 8 ≤ 72

5n ≤ 80

n ≤ 16

n ≤ 16 marbles

So, Iggy has 16 marbles or less.

Answer: Iggy has 16 marbles or less.
