step-by-step explanation:

10.50 + taxes which added up to 11.50

16.9 times 2.85

step-by-step explanation:

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9

answer: yes, since the line has a steeper rate of change than the exponential the y-values will be greater and they will only intersect one time.
