You spend $30 20 on 4 CDs Each CD costs the same amount and is on sale for 80% of the original price 2 Write and solve an equation to find how much you spend on each CD. Let p represent the price you pay for each CD
Equation QS-2240
You spent $ 5.5 on each CD
The next day, the CDs are no longer one sale You have $25. Will you be able to buy 3 more CDS?
Yes you will
be able to buy 3 more CDs
Explain your reasoning for part b).
Each CD COSTS
at the regular price, so 3 CDs would cost $

You will only be able to buy two at the original price the following day.

Step-by-step explanation:

You spend $30.40 on 4 CDs. Each CD costs the same amount and is on sale for 80% of the original price.

If x = original cost of one CD

80% of one CD = 0.8x

0.8x = the price you pay for one discounted CD

You buy 4 of the discounted CDs for $30.40

4(0.8x) = 30.40

solve for x, the original cost of one CD

3.2x = 30.40

x = 9.50

The next day, the CDs are no longer one sale. You have $25. Will you be able to buy 3 more CDs?

25$ / $9.50 = 2.63 CDs

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
