Answer:
$1.25
Step-by-step explanation:
Set up a proportion, use inverse operations, and solve;
cups : price
4 : 5
/4 /4
1 : 5/4
1 : 1.25
1 cup to $1.25
3x + 1 is the length for one side. Do you also need to solve for x?

<span>First year is 30,000.
</span><span>Earn 5% raise every year.
</span>Growth factor is 1.05 this sounds a lot like a geometric ratio.
An = A1 × r^(n-1)Sn = A1 × (1 - r^n) / (1-r)<span>n = 40
A1 = 30,000
A40 = $30,000 * 1.05^39 = $201,142.53
S40 = A1 * (1 - 1.05^40) / (1-1.05) which becomes:
S40 = 30,000 * -6.039988712 / -.05 which becomes:
</span>S40 = -181,199.6614 / -.05 which becomes:
S40 = $3,623,993.227
<span>The individual yearly calculations are shown below: </span>
-13x + 3 is decreasing and has a negative slope.
