Question

A concession stand vendor counts the money in the register. After 1h, it has $42.75. After 5h, it has $260.75. How much money will be in the register at the end of an 8- hour shift?

Answer 1

(1,42.75) (5,260.75) 

260.75-42.72= 218.03
 5-1= 4

218.03/4= 54.5075 

260.75=5(54.5075)
260.75= 272.5375
-272.5375= -11.7875y=54.5075x-11.7875

y=54.5075(8)-11.7875
y=424.27?
