Can someone help me with this pleaseeeeeee and no links :( :(

Answer:
a) 17 Weeks
b) $82
Step-by-step explanation:
a) 500-177=323
So, 323/19 = 17
So, he has been saving for 17 weeks.
b) 17+5=22
So, after 5 weeks he will get 5*19=95
So, 323+95=418
So, 500-418=82
Hence, he will need $82
Hope this helps you. :)
