(a)

Answer to Problem 15IP
Total Income of Anna is
Explanation of Solution
Given:
Anna and Cole each earn x cents per news paper that they deliver, plus tips. Anna delivered 55 news papers and earned $12 in tips. Cole delivered 68 newspapers and earned $15 in tips.
Concept Used:
Rule:
Calculation:
Anna delivered 55 news papers and earned $12 in tips.
Anna earn x cents per news paper that they deliver,
Income from 55 newspaper =
Amount of Tips = $12.
Total Income of Anna =
Thus, total Income of Anna is
