Bobby goes to one store and finds a Christmas tree for $49.99. The store is having a 20% off sale. Bobby decides to go across the street to another store and finds the same tree for $54.99. This store is having a 25% off sale. What is the difference in the sale prices for the tree?

1.24

Step-by-step explanation:

first multiply 20% and 49.99= 10

subtract 10 from 49.99= 40

multiply 25% and 54.99= 13.75

subtract 13.75 from 54.99= 41.24

subtract 41.24 and 40= 1.24

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
