Answer: N=800/5
N=160
He needs to save $160 every week to get $800 in 5 weeks
hope this helps.
So
x=hours
y=pay
use a piecewise function maybe
for x≤40, use y=21x
for x>40, use 840+1.5(21(x-40))
k, sso 46>40 so
840+1.5(21(46-40))
840+1.5(21(6))
840+1.5(126)
840+189
1029
A. 840+1.5(21(x-40))
B. $1029
