Wally blew 1/4 of his income last week on video games and 1/8 on fast foo. If he spent a combined $84 on these things, what was his income last week?

Question

Translate the word p into an equation then solve. Please help!!

Answer 1

Wally spent a total of 1/4 + 1/8 = 2/8 + 1/8 = 3/8 of his total income on these things.

 

84 is 3/8 of what number?

 

Let's call that unknown number x.

 

(3/8) * x = 84

 

3x = 672

 

x = 224

 

Wally's income last week was $224
