Aminah had $120. She spent 20%of the money of food and 25% of the remaining on clothes. What percent of the money did she saved? How much money did she have left?

percent of the money did she saved: 72/120= 60 % or 0.6

72 dollars left

Step-by-step explanation:

She spent 20%of the money of food : 120*0.2= 24 dollars

120-24=96 dollars left

96-24=72 dollars left

percent of the money did she saved: 72/120= 60 % or 0.6

72 dollars left

the difference between a number and 5 is -2.

step-by-step explanation:

notice that the equation you are given has -2 (negative 2) on the right side, not 2. when you subtract 5 from a number n, you are finding the difference between the number and 5.

the difference between a number and 5 is -2.

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
