Joanna works two days eachweek at an afterschool job andsets aside money each day sheworks. She saves $4 on Mondaysand $6 on Wednesdays. Howmany weeks would it take her tosave $60?



Answer :

Joana saves $4 on Mondays and $6 on Wednesdays.

Therefore, in a week, the amount of money Joana will save is

[tex]6+4=\text{ \$10}[/tex]

Let n be the number of weeks it will take Joana to save $60.

Then,

[tex]\begin{gathered} 10n=60 \\ \text{ Dividing both sides by 10, we have} \\ \frac{10n}{10}=\frac{60}{10} \\ n=6 \end{gathered}[/tex]

Hence, the number of weeks it would take her to save $60 is

6 weeks
