Answer: 6 hours
Step-by-step explanation: If you write an equation for this scenario it would be y = 12+3x. 12 is the starting value and x represents how many hours the bike is rented, therefore 3 dollars would be added to the initial 12 each hour. So if Lucy spent $30 then it would change to 30= 12+3x. Now you essentially just need to work backwards. Rearrange the equation and move 12 to the left of the equal sign to make 30-12=3x. Combine vairable to make 18=3x. Divide 3x by 3 to isolate x and divide 18 by 3 as well to make it even. This looks like 18/3=3x/3. Meaning it would end up as 6=x.
If the distance around the earth means circumference, it is, 24,887.64.(not rounded.) C=pi D (pi=3.14 + d=diameter)
Answer:
(a) Equations for both
--- lifeguard
--- camp counselor
(b) Total pay for 5 days
Lifeguard pays $800
Camp counselor pays $375
(c) Which pays more
Lifeguard job pays more
Step-by-step explanation:
Let


Given
Lifeguard job


Camp counselor job


Solving (a): The equation for both
The total pay for each job is calculated as:
Total Pay = Signing Bonus + Rate * Hours
So, we have:
Lifeguard


Camp counselor


Solving (b): Total pay for 5 days
First, we calculate the total hours worked in 5 days


So, the pay for each is:


--- Lifeguard


--- camp counselor
Solving (c): Which job pays more
By comparing the solution in (b)

<em>Hence, lifeguard job pays more</em>
