Enter the following grade report into an empty Excel worksheet. Place the heading (Grade Report) in cell Al. (The numerical grades correspond to letter grades, i. e., A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0. Fractional values represent pluses and minuses, i. e., A- = 3.7, B+ = 3.3, B- = 2.7, etc.). Don't enter or calculate letter grades. Be sure that all of the strings (text) are fully visible within the worksheet. Calculate the average grade WEIGHTED BY CREDITS and show formulas. For example, the average of 3.0 for a 4 credit class and 2.0 for a 3 credit class is (3*4+2*3)/(4+3 credits) = 2.57, NOT 2.5. Copy and paste your cells into the answer. Show data and formulas. The easiest way is to copy and paste data, then show formulas and copy and paste again.

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
