-10-8a=8-10a
+10 +10
-8a = 18-10a
+10a +10a
2a = 18
2 2
a = 9

to find the number of subscribtion sold we divide the money she made by the price of subscription
monday:
42.80/5.35=8 subscriptions sold
tuesday:
64.20/5.35=12 subscriptions sold
wednesday:
74.90/5.35=14 subscriptions sold
8+12+14=<u><em>34 subscriptions sold in 3 days</em></u>
