Answer:
James makes $12 less each month than Matt.
80 - x
12(80 - x) = 816
Step-by-step explanation:
Matt makes $80 per month.
Jame makes x dollars less than Matt per month,
so James makes $80 - x per month.
In one year, Matt makes 12 * $80.
In one year, James makes 12 * (80 - x), and he makes $816,
so 12(80 - x) mus equal 816.
12(80 - x) = 816
960 - 12x = 816
-12x = - 144
x = 12
James makes $12 less each month than Matt.
Answer:
James makes 12 dollars less per month than Matt
James = 80-x per month
Step-by-step explanation:
Matt = 80 per month
James = 80-x per month
To determine what James makes per year, multiply by 12 months
Earnings of James per year = 12(80-x)
                       = 960 -12x
James makes 816 per year
                  816 = 980-12x
Subtract 980 from each side
            816-980 = 980-980-12x
                 -144= -12x
Divide by -12
                -144/-12 = -12x/-12
                     12=x
James makes = 80-x per month
            = 80-12
             = 68 per month
