Answer:

he was there 3 hours

Step-by-step explanation:

so you take 160 and subtract 55 from that number

160-55=105

next take 105 and divide that by 35 to get how many hours he was there.

105÷35=3

if you need this in slope intercept for a graph you use the equation where y = the total money spent

y=35x+55
