Jill has $1.25 in her pocket. The money is in quarters and dimes. There are a total of 8 coins. How many quarters and dimes does
erica [24]

Answer:

  • 3 quarters
  • 5 dimes

Step-by-step explanation:

Let q represent the number of quarters (the higher-value coin). Then 8-q is the number of dimes, and Jill's total amount in change is ...

  0.25q +0.10(8-q) = 1.25

  0.15q + 0.80 = 1.25 . . . . . . . eliminate parentheses

  0.15q = 0.45 . . . . . . . . . . . . . subtract 0.80

  q = 3 . . . . . . . . . . . . . . . . . . . . divide by 0.15

  the number of dimes is 8-q = 8-3 = 5.

Jill has 3 quarters and 5 dimes.

300 tickest sold
total=300
a+s=300


value=rate times number of peple

student value=4s
adults value=10a
total value=1950
4s+10a=1950



a. system of equations are
s+a=300
4s+10a=1950



b. solve

s+a=300
4s+10a=1950

a+s=300
multiply by -4
-4s-4a=-1200
add to other eqaution

4s+10a=1950
<u>-4s-4a=-1200  + </u>
0s+6a=750

6a=750
divide 6
a=125


subsiute
s+a=300
s+125=300
subtract 125
s=175
