Allison earned $200 the first month she worked and $250 the second month she worked. By what percent did her salary increase?

25%

Step-by-step explanation:

From the question, we are informed that Allison earned $200 the first month she worked and $250 the second month she worked.

The percentage increase in her salary will be calculated as:

= Salary Increase / Old salary × 100

= (250 - 200) / 200 × 100

= 50/200 × 100

= 1/4 × 100

= 25%

The percentage increase is 25%

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
