Answer:
3 nights
Step-by-step explanation:
Set up an equation that represents the problem:
y = 1.25x + 3.95
Where y is the total cost and x is the number of additional nights you rent the movie
Substitute:
7.70 = 1.25x + 3.95
Subtract 3.95 on both sides:
7.70 = 1.25x + 3.95
-3.95 -3.95
3.75 = 1.25x
Divide by 1.25 on both sides:
3.75 = 1.25x
/1.25 /1.25
3 = x
Therefore, you kept the movie for 3 additional nights.
Answer:
<span>y=4.98</span>
Explanation:
First, find the constant of proportionality , k.
<span>y=kx</span>
<span>21=7k</span>
<span>k=3</span>
We now start over and solve for y using the new value of x and the obtained value of k.
<span>y=<span>(3)</span><span>(1.66)</span></span>
<span>y=<span>4.98</span></span>
