Answer:
55
Step-by-step explanation:
1st you would find the equation which would be (16 + 6.50x) = (10 + 7.50x) then you would find the answer which would be x = 6 then you would do 6.50 times 6 which would give u 39 add that to 16 which is 55 and do the same on the other side (7.50 times 6) which would give u 45 and then add the 10 which is 55 so the answer is 55.
Answer:
No.
Step-by-step explanation:
The numbers aren't going up at a constant rate. Say each lap costs 2 dollars. On lap 4, you have paid 8 dollars total. On lap 9, you have paid 18 dollars total. But the 10th lap is free, which means you pay 0 dollars. In order for this pattern to be constant, you would need to pay 20 dollars, but instead you pay 0.
