1/3 cup of flour is used to make 5 dinner rolls.
RoseWind [281]

we know that

\frac{1}{3} cup of flour is used to make 5 dinner rolls.

Part a) How much flour is needed to make one dinner roll?

by using proportion

\frac{\frac{1}{3}}{5}  =\frac{x}{1} \\ \\ x=\frac{\frac{1}{3}}{5}\\ \\ x=\frac{1}{15}

therefore

the answer Part a) is

To make one dinner roll is needed \frac{1}{15} cup of flour

Part b) How many cups of flour are needed to make 3 dozen dinner rolls?

Multiply the value obtained in part a) by 36

so

\frac{1}{15} *36=\frac{36}{15} \\ \\ =\frac{12}{5}

\frac{12}{5} =2\frac{2}{5}

therefore

the answer Part b) is

To make 3 dozen dinner rolls are needed 2\frac{2}{5} cup of flour

Part c) How many rolls can you make with 5 2/3 cups of flour?

5\frac{2}{3} =\frac{17}{3}

by using proportion

\frac{\frac{1}{3}}{5}  =\frac{\frac{17}{3}}{x} \\ \\ \frac{x}{3} =\frac{85}{3} \\ \\ x=85

therefore

the answer part c) is

85 rolls

100 points Help my grades depend on this
ipn [44]
She earned 1149, which is between 436 and 1506 so you would use the 2nd row for the information.

the tax rate says 15% for the amount over 436
 so fist find the amount that is taxable:

1149 - 436 = 713
 now multiply that amount by 0.15 ( 15% as a decimal)

713 * 0.15 = 106.95

now add the base tax to that amount for the total amount of tax:  
106.95 + 34.90 = 141.85 total tax withheld
