Question

Jenny started with $4 in her piggy bank and earns an allowance of $3 every 2 days. Mika had saved $18 in his piggy bank from babysitting but he spends $2 a day to buy a large bag of chips on his way home from school.When will Jenny and Mika have the same amount of money?

Answer 1

14/5

Explanation:

J = 3x+4

M = 18-2x

3x+4=18-2x

5x= 14

x=14/5

or

18-2x=3x+4

-5x = -14

x= 14/5
