Which isn't the least expensive per oz rounded to the nearest cent 20oz for $1.79 or 2 pounds 2 oz for $2.59

This problem calls for calculating the unit cost in each case and then comparing the unit costs.

$1.79

= $0.09/oz

20 oz

Noting that 1 lb = 16 oz,

$2.59

= $0.14

18 oz

$1.79 for 20 oz is definitely the better buy (less expensive) when compared to $2.59 for 18 oz.

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
