12 bro it even says to follow the order of operations. If there is only addition and subtraction you just go from left to right. Same with if there is only multiplication and division.
Given,
The salary for the technician from shop A is $900 per week.
The salary for the technician from shop B is $25 per hour.
The equation for the total pay for shop B is,

Taking the total pay as 900. As, to make the shop A and shop B equal.

Hence, he would have to log 36 hours during a week at Shop B in order to match the salary at Shop A.
Answer:
y= $50x + $25
Step-by-step explanation:
Slope-intercept form is y=mx+b
x is something that is constant
b is something you add on to the constant
8*.8=6.4
4x+6.4=40
40-6.4=33.6
33.6/4=x
8.4=x
Hope this helps :)
