Answer: The number is 7

Step-by-step explanation:

Let x be the [number]

Rephrase the expression

2 times a number is increased by 4, it is the same as 25 decreased by the number

2x+4=25-x

Calculate

Given

2x+4=25-x

Add x on both sides

2x+4+x=25-x+x

3x+4=25

Subtract 4 on both sides

3x+4-4=25-4

3x=21

Divide 3 on both sides

3x/3=21/3

x=7

Hope this helps!! :)

Answer: 20% increase

Reasoning: Going from fifty to sixty is an increase of ten, with respect to the original fifty pairs.

The percentage increase should be calculated from change/original x 100%

10/50 x 100% would equal 20%, which in this case 20% would be the increase, which is your answer, known as B. Hope I helped! If not, at least I tried.
