Answer 1

Answer:

2hours

Step-by-step explanation:

Step one:

given data

Rental #1

charges a flat fee of $1 with an additional cost of $2 for every hour

let the number of hours be x

the total charge

y= 1+2x-------------1

Rental #2

charges a flat fee of $3 with an additional cost of $1 for every hour.

let the number of hours be x

the total charge

y= 3+1x-------------2

equate 1 and 2

1+2x=3+x

collect like terms

1-3=x-2x

-2=-x

x=2hours
