Given function:
y=-7.3x+39.7
Where y= number of gallons of water
and x= number of minutes
Put value of y=17.8 gallons and solving for x.
17.8=-7.3x+39.7
Subtract 39.7 from both sides
-21.9=-7.3x
Divide both sides by -7.3
3=x
or
x=3 minutes
After 3 minutes the water in the tub will be 17.8 gallons.
Answer: 3 minutes
If you would like to know what is the selling price of the sweater, you can calculate this using the following steps:
40% of x is $8
40% * x = 8
40/100 * x = 8 /*100/40
x = 8 * 100 / 40
x = $20
Result: The selling price of the sweater is $20.
