Answer:
Ace bike hourly rate is $3.5 per hour
Bart bike hourly rate is $3.0 per hour
It is lower by rate $0.5 per hour
Explanation:
Ace bike:
Ace bike rentals rents bikes for $28 per day
Rental price =$28
Renters can keep the bike for 8 hours
so, total time in a day =8 hours
now, we can find hourly rate
hourly rate = (Rental price)/( total time in a day)
now, we can plug values
hourly rate is
![=(28)/(8)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/jiautdklzrawpliq0czuzp5mo0fao2uai7.png)
=$3.5 per hour
Bart bike:
Bart bike rentals rents bikes for $30 per day
Rental price =$30
Renters can keep the bike for 10 hours
so, total time in a day =10 hours
now, we can find hourly rate
hourly rate = (Rental price)/( total time in a day)
now, we can plug values
hourly rate is
![=(30)/(10)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/h4dyodxgjjdi3x0655u4ye3pt95uqxiozh.png)
=$3 per hour
so, changed hourly rate
=Ace hourly rate - Bart hourly rate
we can plug values
![=3.5-3](https://img.qammunity.org/2020/formulas/mathematics/middle-school/tthunvq7i66utrw9qtpx1ez8w8i9m7dsfu.png)
![=0.5](https://img.qammunity.org/2020/formulas/mathematics/middle-school/qpolcoqgqcskfhk6iqormc3bds2oqd9dhv.png)
So, it is lower by rate $0.5 per hour
