After 4 weeks, Macy and Robby will have same amount in their accounts.
Step-by-step explanation:
Given,
Amount saved by Macy each week = $12.50
Let,
x be the number of weeks.
M(x) = 12.50x
Amount saved by Robby each week = $7.50
Amount Robby already have = $20
R(x) = 7.50x + 20
For same amount;
M(x) = R(x)
Dividing both sides by 5
After 4 weeks, Macy and Robby will have same amount in their accounts.

Answer:
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:
