Abdul purchased a prepaid phone card for 45.00 . calls cost 6 cents a minute using this card. the credit, (in dollars), left on the card after it is used for x minutes of calls is given by the following. c= 45.00 - 0.06x how much credit is left on the card after abdul uses it for 50 minutes of calls?

C= 45.00 - 0.06x

C= 45.00 - 0.06(50)

C= 45.00 - 3 = $42 left

hi,

6x times 4 is 24x and 5 times 4 is 20, so the answer is 24x+20.

hope this and for a little humor i am groot.

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.
