Answer:
The independent variable is the number of cars
the band washes and the dependent is the number of money they earn
Step-by-step explanation:
19n-57=76
You must get "n" by itself
19n-57+57=76+57 (add 57 to each side)
19n=133
Divide 133 by 19
133÷19=7
n=7
20+16+18+14+9+20+16=113
113÷7=16.14285714
after rounded the answer would be 16.
hope that's correct.
