Translate the sentence into an equation using n as the unknown number. Then solve the equation for n

Two times a number increased by 5 is 15.

a.

2n (5) = 15

n = 1.5

c.

2n + 5 = 15

n = 20

b.

2n + 5=15

n = 5

d.

n + 5 = 15

n = 10

The correct answer is b.

2n + 5=15

n = 5

This is because when you put the word problem into a numerical equation, you get 2n+5=15. To simplify this, you subtract 5 from both sides, resulting in 2n=10. Then you divide both sides by 2, and you get n=5.
