72 is equal to 80% of a number n. write and solve and equation to find n. write the percent as a decimal.

n = 90

Step-by-step explanation:

To solve this, we need to write the questions mathematically and then solve

72 = 80% of n

72   = ×  n

72  =  

Multiply both-side of the equation by 100

72 × 100 =     ×100

At the right-hand side of the equation, 100 will cancel-out 100, leaving us with just 80 n

7200 = 80 n

Divide both-side of the equation by 80

 =  

(On the right-hand side of the equation, 80 will cancel out 80 leaving us with just n while on the left-hand side of the equation 7200 will be divide by 80)

  =   n

90  =  n

n = 90

your answer is d 2,500
