Ineed on this

round and estimate only 74(711
and 22(890

i've been stuck on this for 4 hours i cant learn well

for how many digits is rounding required to occur?

if it's one digit, it should be 70,000 and 20,000

if it's two digits it would be 75,000 and 23,000

if it's three digits it would be 74,700 and 22,900

if it's four digits it would be 74,710 and 22,980

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
