Step-by-step explanation:
The rate of change is a measure in which one variable is modified in relation to another. In this case we have the variables:
Temperature in
Time in
Now, to calculate the rate of change, we have to divide one variable by the other. In this case the change in temperature divided by the time variation
.
Hence, assuming the ambient temperature of the glass is and the elapsed time
we have:
Their earnings would be the same after 4 hours
Let the number of hours be x, and the weekly earning be y
So, the given parameters are:
<u>Kimi</u>
- Earnings = $9 per hour
- Weekly allowance = $8
So, the equation for Kimi's weekly earning is:
<u />
<u>Jordan</u>
- Earnings = $7 per hour
- Weekly allowance = $16
So, the equation for Jordan's weekly earning is:
Equate both equations
Collect like terms
Divide both sides by 2
Hence, their earnings would be the same after 4 hours
