Quality Cleaners decides to raise the price of dry cleaning a vest from $5 to $6. The same percent increase is applied to dry cleaning a dress. The old cost of dry cleaning a dress is $12. What is the new cost of dry cleaning a dress?

$14.4

Step-by-step explanation:

The original price of dry cleaning a vest = $5

The new price of dry cleaning a vest = $6

The percentage increase is obtained by

× 100

×100 = 20%

hence, there is a 20% increase in price.

applying this 20% increase to the cost of dry cleaning, the new cost will become

×12

this is a 120% increase in cost.

mathematically this can be solved by

×12 = $14.4

hence, the new cost of dry cleaning is $14.4

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 !

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10
