For the first one the slope is 0.5
For the second one the slope is -1.7
Answer:
Step-by-step explanation:
d + q = 94.....d = 94 - q
0.10d + 0.25q = 19.30
0.10(94 - q) + 0.25q = 19.30
9.4 - 0.10q + 0.25q = 19.30
-0.10q + 0.25q = 19.30 - 9.40
0.15q = 9.90
q = 9.90/0.15
q = 66 <===== there are 66 quarters
d + q = 94
d + 66 = 94
d = 94 - 66
d = 28 <==== there are 28 dimes

Answer:
The principle amount = $4000
Step-by-step explanation:
Formula:
Simple interest I = PTR/100
P - Principle amount
T - Number of years
R - Rate of interest
<u>To find principle amount</u>
Here , P = ?, T = 2 years, R = 5.9% and p + I = $4472
I = PTR/100
P + (P*2**5.9)/100 = 4472
P[1 + 11.8/100] = 4472
P[111.8/100] = 4472
P = (4472*100)/111.8 = 4000
Therefore the principle amount P = $4000
