Answer: She has 76 dimes and 78 quarters.
Step-by-step explanation:
Given data:
Total = $27.20
Solution:
Q = d + 2
Each quarter is 25 cents, or 0.25 of a dollar = 0.25q
Each dime is 10 cents = 0.10d
0.25q+0.10d = $27.20
Where q = d-2
Substitute in this equation:
0.25(d+2)+0.10d = 27.20
0.25d + 0.5 + 0.10d = 27.20
0.35d = 26.7
Divide both sides by 0.35
d = 76
She has 76 dimes and 76 + 2 = 78 quarters.

Answer:
11/2
Step-by-step explanation:
5y+3=36-y
1) Subtract 3 from both sides:
5y=33-y
2) Add y to both sides:
6y=33
3) divide both sides by 6:
y=33/6
4) Simplify the fraction:
11/2
