Jack worked for 3 1/3 hours and earned $20.70. How much would he make if he worked for 4 1/4 hours?

So,

20.7 = (3 1/3) x

x represents the amount he earns per hour.

To solve for x, use inverse operations and divide both sides of the equation by 3 1/3.

(3 1/3) x divided by 3 1/3 equals x

20.7 divided by 3 1/3 equals 6.21.

He earns $6.21 per hour.

To get how much money he earns in 4 1/4 hours, you have to multiply 6.21 by 4 1/4. This would equal 26.3925. However, we need to round it to the nearest cent.

26.3925 rounded to the nearest cent is 26.39.

Jack would make $26.39 in 4 1/4 hours
