Answer 1

Part 1

Find out the unit rates

Matte Paint

7.56/4=$1.89 per pint

Glossy Paint

26.16/2=$13.08 per gallon

Paint Brushes

18/4=$4.5 per brush

therefore

Verify each statement

option A

If he buys 1 1/2 gal on matte paints

1 1/2=1.5 gal

1.5*1.89=$2.84

statement A is not true

option B

Convert quart to gal

1 quart=0.25 gal

6 quarts=1.5 gal

1.5*13.08=$19.62

statement B is true

option C

2 paintbrush ------> 2*4.5=$9

1 gal matte paint

convert gal to pint

1 gal=8 pint

8*1.89=$15.12

15.12+9=$24.12

statement C is true

Option D

13 pints of glossy paint

$13.08 per gallon

1 gal =8 pint

13 pints=13/8 gal

(13/8)*13.08=$21.26

statement D is not true

the answer is options B and C
