Answer:
23 weeks
Step-by-step explanation:
For 1 week he can learn 2 new pieces. He wants to pay 46 pieces. So we would make the following equation:
[tex]2x=46[/tex] where x is equal to the number of weeks
We can then solve for x by dividing 46 by 2.
[tex]\frac{46}{2} =23[/tex]
So in order for Justin to learn 46 pieces, it would take 23 weeks.
