Answer:
Subtracted 3 from (24+3)
Step-by-step explanation:
3m - 3 + 3
24 - 3 + 3
Since the adding and subtracting go left to right, you can do them in that order.
21+3 = 24.
Now which one gives us 24?
(24+3) - 3
For this case, the first thing we must do is define variables:
x = number of quarters
y = number of dimes
We now write the system of equations:
x + y = 28
0.25x + 0.10y = 4.05
Solving the system of equations we have:
x = 8.33
y = 19.66
Rounding:
x = 8
y = 20
