Answer:
$20,000
Explanation:
Step one:
we are told that the base salary is $24000
and also earns 8% of the total sale
let the total sales be x
additional earnings= 0.8x
the linear function for this situation is given as
y=0.8x+c
where y= the expected earning
x= sales
c= is the base salary
40000=0.8x+24000
solve for x
40000-24000=0.8x
16000=0.8x
divide both sides by 0.8
x=16000/0.8
x=20000
He needs to make sales of at least $20,000
