Bridgett is buying snacks for her club meeting. she wants to buy a box of crackers for $3.79, a bag of fruit for $6.79, and some cheese for $4.62. she has $20 to spend for snacks. which statement best describes whether an exact total or an approximate total should be calculated? a. bridgett can round the prices of the snacks to the nearest dollar and then add to estimate if she has enough money. b. bridgett must add the 3 amounts exactly so she will know if she has enough money to buy the snacks.

answer: i believe its b. if you sound out the sentences that sounds wrong.

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
