Answer:
1st: 2x
2nd: 2x+2
--------
Equation:
4(2x) = 3(2x+2)
-------
8x = 6x + 6
2x = 6
x = 3
-----
1st 2x = 6
2nd: 2x+2 = 8
Step-by-step explanation:
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

Answer:
The cost of the dinner before other costs is $14.20
Step-by-step explanation:
To solve this, we write the following equation:
x + .11x + .20x = 18.60
This is because in addition to paying for the dinner (x), she also has to pay 11% of it and another 20% of it. Now we can combine like terms and solve.
1.31x = 18.60
x = 14.20
