McDonalds sells 6 times as many orders of French fries as Harry's Hamburger Hut every day. If both sold 60 more orders McDonalds would sell only 3 times as many fries. How many orders of fries do each sell before and after the increase?

Let x be the orders Harry sold

y be the orders McDonal sold

x + y = 60 (1)

and y/x = 3 (2)

s0lve this system x =15, y =45

after increase

H. sold 15+15 =30

Mc. sold 15*6 + 45 = 135

M = 6H

if each sold 60 more ...

M+60 = 3(H+60)

6H + 60 = 3H + 180

3H = 120

H = 40

M = 240

check: after increase

H = 100

M = 300

is 300 three times 100 ?

check!!
