Answer: A(t) = (6.4 ft^2/min)*t
Step-by-step explanation:
We know that Emily paints at a constant rate, and she can paint 32 ft^2 in 5 minutes.
Then if we take the quotient of these two quantities, we will find the amount she can paint in one minute, this is:
32ft^2/5min = (32/5) ft^2/min = 6.4 ft^2/min.
Then if she paints for t minutes, the area that she can cover can be written as:
A(t) = (6.4 ft^2/min)*t
This is the linear equation we wanted to find.
It would be 16/7, or 2 2/7 as a mixed number. Correct me if i'm wrong :)
Answer:
$60
Step-by-step explanation:
30% * x = 18
3/10 * x = 18
x = 18 * 10/3
x= 60
