You have $60 in your wallet and want to buy some new CDs. If the CDs are $11 each, what number of CDs, x, can you buy? Write and solve an inequality. Then explain your answer.

My Answer:

11x <= 60
divde by 11
x <= 60/11 or 55/11

x is an integer
x<=5

5 CD's, which will cost $55
6 would cost $66, which is too much.

Arrgh, scroll down I did this

11 x = 60
x = 5.45
but you can not buy .45 of a CD
so you can only buy 5

Wendy, you did it great!

Damon, you are supposed to write an inequality as stated in the problem. You wrote an equation.

Thank You Katalina! And Damon I said check my work not give me the answer! But thanks anyway!both of 2

To solve this problem, we can start by setting up an inequality. Let x represent the number of CDs you can buy. Since each CD costs $11, the total cost of the CDs can be found by multiplying 11 and x, which gives us 11x. Since you have $60, we can set up the inequality 11x ≤ 60.

To solve this inequality for x, divide both sides of the inequality by 11. This gives us x ≤ 60/11 or 5 and 5/11.

However, since we are dealing with a real-life scenario, the number of CDs must be a whole number. Therefore, we round down to the largest whole number less than or equal to 5 and 5/11, which gives us x ≤ 5.

So, you can buy a maximum of 5 CDs with $60.
