Step-by-step explanation:
too lazy to explain :/
Graphing is a good method when you have small integers or fractions as your slope.
Substitution is a good method when you have two equations, and when one of the coefficient of the variables is one.
Linear combinations is a good method when you have the same coefficient for the same variable in 2 different equations.
115% of the price is 270,25
115*x/100=270,25
x=270,25*100/115
x=235 $ is the price
270,25-235= 35,25 $ is the tax
$8x24=200
22% of 200 is 44 dollars
you said she gets paid 4 times a month so therefor 44x4 = 176
