The histogram shows he number of miles that each adult, from a survey of 111 adults, drives per week. How many adults drive free than 150 miles per week?

There are __ adults

There are 71 adults drive fewer than 150 miles per week.

Solution:

From the histogram given,

Number of miles   Number of adults

    0 – 49                              17

  50 – 99                             28

 100 – 149                            26

 150 – 199                            19

200 – 249                             1

250 – 299                           20

Fewer than 150 miles means below 150 miles.

Number of adults drive fewer than 150 miles = 17 + 28 + 26

                                                                           = 71

Number of adults drive fewer than 150 miles = 71

There are 71 adults drive fewer than 150 miles per week.

f

step-by-step explanation:

f

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
