Heather, Michael, and Austin have a total of 92 in their wallets. Heather has 10 more than Michael. Austin has 4 times what Heather has. How much do they have in their wallets?

Heather - 17, Michael - 7, Austin - 68

Step-by-step explanation:

h + m + a = 92

h = m+10 ⇒ m = h - 10

a = 4h

h + h-10 + 4h = 92 6h = 92+10 6h = 102 h = 102/6 h = 17 ⇒ m = 17-10 = 7, a = 4*17 = 68

Heather - 17, Michael - 7, Austin - 68

Austin - 68

Healther - 17

Michael - 7

Step-by-step explanation:

x+x-10+4x=92

6x=102

x=17
