Madison worked for 7.5 hours before school and 15 hours after school

<em><u>Solution:</u></em>

Given that, Madison works a job before and after school

Amount earned before school = $ 11.50 per hour

Amount earned after school = $ 11.75 per hour

Amount earned last week = $ 262.50

Let "x" be the hours worked before school

Given that, she worked twice as many hours after school

So, number of hours worked after school = 2x

Therefore, we can say,

Total amount earned = (Amount earned before school)(number of hours) + (Amount earned after school)(number of hours)

262.50 = 11.50(x) + 11.75(2x)\\\\262.50 = 11.50x + 23.5x\\\\35x = 262.50\\\\x = 7.5

Number of hours worked after school = 2x = 2(7.5) = 15

Thus Madison worked for 7.5 hours before school and 15 hours after school

How many gallons of a 50% antifreeze solution must be mixed with 60 gallons of 30% antifreeze to get a mixture that is 40% antif
Mariulka [41]

I don't know what the "six-step method" is supposed to be, so I'll just demonstrate the typical method for this problem.

Let <em>x</em> be the amount (in gal) of the 50% antifreeze solution that is required. The new solution will then have a total volume of (<em>x</em> + 60) gal.

Each gal of the 50% solution used contributes 0.5 gal of antifreeze. Similarly, each gal of the 30% solution contributes 0.3 gal of antifreeze. So the new solution will contain (0.5 <em>x</em> + 0.3 * 60) gal = (0.5 <em>x</em> + 18) gal of antifreeze.

We want the concentration of antifreeze to be 40% in the new solution, so we need to have

(0.5 <em>x</em> + 18) / (<em>x</em> + 60) = 0.4

Solve for <em>x</em> :

0.5 <em>x</em> + 18 = 0.4 (<em>x</em> + 60)

0.5 <em>x</em> + 18 = 0.4 <em>x</em> + 24

0.5 <em>x</em> - 0.4 <em>x</em> = 24 - 18

0.1 <em>x</em> = 6

<em>x</em> = 6/0.1 = 60 gal
