Answer:
8X+.07Y=W
Step-by-step explanation:
x is your hours and y is your sales
he makes 8 an hour, hence 8X or 8 x X
7 percent written as a decimal is .07 and his commission for sales, so .07Y
add them together and you get your equation:
8X+.07Y=W
We know that
<span>A large pump can drain an 80,000 gallon pool------------> in 3 hours
X gallons---------------------------------------------------------> in 2 hour
X=2*80000/3----------> 53333.33 gallons in 2 hour
therefore
</span><span>the smaller pump in two hours drain an [80000-53333.33]=26666.67 gallons
</span><span>
if the </span>smaller pump drain 26666.67 gallons-----------------> in 2 hours
<span> 80000 gallons------------------------------------------------> X
X=80000*2/26666.67------> 6 hours
the answer is
</span><span>the smaller pump to drain the pool by itself would take 6 hours</span><span>
</span><span>
