Answer:
25 +15x
Step-by-step explanation:
so the fee to rent a truck is 25 but for every hour that you have it, you have to pay $15, so x represents the number of hours you have the truck, so if you have the truck for 3 hours, you would say 25+15(3)= $70
27-4=23-4=19-5=14-4=10-5=5-5 ( 3 pizzas and 3 videos)
Call b the amount of babysitting hours and 5 the amount of gardening hours.
10b+5g=80
b+g=12
Subtract 5 times the second equation from the first to get:
5b=20
Thus, b=4. g=12-4, or 8. Therefore, Sarah spends 4 hours babysitting and the rest gardening.
