Answer:
$125
Step-by-step explanation:
if there was a discount of 20%, the sales price is 100 - 20 = 80% of the original price
let a = original price
this equation can be used to represent the question
a x 0.8 = 100 ]]divide both sides by 0.8
a = 100 / 0.8 = 125
Answer:
Equation 1,
Equation 2,

angle Y=180-50=130
An increase of 2% per year means the population is multiplied by 1.02 each year. Your exponential function with a base of 1.02 and a scale factor of 5.3 (billion) will look like this:
... q(t) = 5.3×1.02^t
Percent means parts out tof 100 so 15%=15/100
divide by 5/5
3/20=lowet terms
