80 hr total
the assistants is not info
25 hr X $22 per = $500
15 hr X $10 = $150

Answer:
Yes, Mark has $16 left and only has to pay his sister $15.
Step-by-step explanation:
1/5=x/20
use cross multiplication to find (x),which represents 20% of 20.
x/20=1/5 (cross multiply)
20=5x (divide by 5 on both sides)
x=4
This tells you that Mark gave $4 to the local charity.
20-4=16
Subtracting 4 from his original amount, he now has $16 left.
<span>10(4*10÷(6²-4²)+1)
10(40÷(36+16)+1)
</span>10(40÷(52)+1)
10(40÷(52)+1)
10(0.7692307692+1)
10(1.7692307692)
17.692307692
You should probably round that:
17.69
