noel and renaldo want to rent bikes with two other friends. they have $150 to spend on bike rentals.
bike rentals
rent 1 bike for 9.75 per hour.
special group rate
for group of 4 or more, save $3.00 per person.
4(9.75h-3)=150
noel says they have enough money to rent the bikes for a miximum of 3 hours. slove the equations for the number of hours,h, in order to determine whether noel is correct.
4(9.75h-3)=150
39h-12=150
39h=162
h=162/ 39=4.15, which means they can
Afford to rent for 4 hours.
This is for part (A)
4(9.75h-3)=150
39h-12=150
39h=138
39h/39=138/39
3.6 when rounded
THANK U SOOOOOOO MUCH!!
NOO PROBLEM SOO MUCH :D
after
39h-12=150
Christina should have had
39h = 162
h = 4.15 hours
o thankz!!
thank you soo much!-- this really helps! =D
jjhh
that helped alot
To solve the equation, we'll begin by simplifying it step by step.
4(9.75h - 3) = 150
First, distribute the 4 to both terms inside the parentheses:
39h - 12 = 150
Next, add 12 to both sides of the equation to isolate the variable h:
39h = 162
Finally, divide both sides of the equation by 39:
h = 162 / 39
Now, let's calculate the value of h to determine whether Noel is correct:
h ≈ 4.15
Since we cannot have a fraction of an hour, we can round up to the nearest whole number. Therefore, h = 5.
Since h = 5, it means they can rent the bikes for a maximum of 5 hours, not 3 hours as Noel had stated.
