Step-by-step explanation:
25=d+q
4.30= .1d + .25q
25=d+q
-17.20=-.4d+-q
7.80= .6d
d=13...... 13 DIMES
25= 13+q
12=q....... 12 QUARTERS
m = 36
<u>Work</u>
<em>45 + 2.50m = 3.75m</em>
<em> -3.75m -3.75m</em>
<em>45 - 1.25m = 0</em>
<em>- 45 - 45</em>
<u><em>-1.25</em></u><em>m = </em><u><em>-45</em></u>
<em>-1.25 -1.25</em>
<em> </em>m = 36
