Complete question :

store sells posters each poster cost the same amount door I sell the store reduces the price of each poster by $1.25 Kayla spent $17.17 on four posters at the sale price. What was the price of one poster before the sale

5.5425

Step-by-step explanation:

Given that:

Price of posters are the same.

Let price of poster before sale = x

Sale on poster = reduction by $1.25

Price on sale = x - 1.25

Amount spent on 4 posters during sale = $17.17

Hence, cost per poster during sale :

$17.17 / 4

= $4.2925

Therefore, cost per poster before sale, x:

Price on sale = x - 1.25

$4.2925 = x - 1.25

x = $4.2925 + $1.25

x = $5.5425

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
