, since she can't buy half a CD, she's limited to no more than 8 CDs. If x = the cost of one CD, then x CDs cost $18x. Since we are limited to $153, our equation looks like... 18x < 153x < 8

Again, since we can't buy half a CD, your answer should actually be... x ≤ 8 since we can buy 8 CDs or fewer.
17% of 400 is 68.
Another way u can do it is 17% of 100 four times since its easier to do.

we have to do this 4 times since 100 goes into 400 four times.
So 17*4 =68
