At Bike Shop X it costs $2.75 per hour plus a $3.00 deposit to rent a bike. At Bike Shop Z it costs $1.75 per hour plus a $7 deposit to rent a bike. When would it cost less to rent a bike
from Bike Shop X? Explain.

ok so you see that right away bike shop x is more cost than bike shop z so if you add 2.75 and 3 dollars it would cost 5.75 dollars of course the cost of 2.75 dollars is per hour so you would need to count 2.75 per hour and as you bike shop z the amount of cost per hour is 1.75 but the deposit fee is 7 dollars so the cost would be 8.75.

Step-by-step explanation:

Ok why it is lower cost because as you  see each hour on shop x it is 2.75 and each hour in z shop it is 1.75 why z shop is lower because x shop have bigger cost per hour and that can add up more than z shop.

you never say the total so we cant find the percentage used for petrol
