The working out I done is wrong but plz help me guys

42.04

Step-by-step explanation:

First we need to crunch the numbers on a calculator to figure out how many packs of rolls vs. how many cheese slices will be over 100.

Since there are 120 cheese slices in 6 packs (six times 20 equals 120)

and there are 120 rolls in 8 packs (8 times 15 equals 120)

Then it says we have to have a double amount of cheese, so we need 12 times 2.23 which equals 26.76

Then figure out how much the cost of the rolls are by multiplying 8 times 1.91 which equals 15.28

Next add the two totals together, 26.76 plus 15.28 is 42.04

42.04 is the least amount she can spend for over 100 sandwiches.

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
