Answer: $16
with the base being $6, you can write the equation 6 + .5x = y
“x” is represented by the number of songs downloaded, so we can replace x with 20
y is the total amount of money
6 + .5(20) = y
now, all you have to do is solve
6 + 10 = y
16 = y
Answer:
x = 30.97 ( to nearest hundredth).
Step-by-step explanation:
5^x = 8^x-7
Taking logs of both sides:-
ln 5^x = ln 8^x
By the law of logarithms:-
x ln 5 = (x - 7) ln 8
x / (x - 7) = ln 8 / ln 5
x / (x - 7) = 1.292
x = 1.292x - 9.044
1.292x - x = 9.044
x = 9.044 / 0.292
= 30.97 (answer)
