"at the end of the year Juan has $52.71 more than 4 times his balance at the beginning of the year if his ending balance was $17

Salsk061 [2.6K]

At the end of the year, Juan has 52.71 more than 4 times his balance at the beginning. Okay, let's set this up.

4x + 52.71
(4 times) (52.71 more)
His ending was 172.90, so
4x + 52.71=172.90
4x= 120.19
x= 30.05
He had $30.05 at the beginning of the year.

An instructor makes $15 more per hour than an assistant. If the combined hourly wage of the instructor and assistant is $65, wha

mezya [45]

X= assistant's wage
x+15= instructor's wage

Add their wages set equal to $65

x + (x + 15)= 65
combine like terms

2x + 15= 65
subtract 15 from both sides

2x= 50
divide both sides by 2

x= $25 assistant's wage

x+15= 25 + 15= $40 instructor's wage

ANSWER: (C) $25 hourly wage of assistant

Hope this helps! :)
