Mikiah must choose between a pack of four 6.5-ounce containers of ice cream for $3.77 or a pack of three 8-ounce containers for $3.87. Which is the better buy? Why?

a pack of three 8-ounce containers his is a better purchase

Step-by-step explanation:

In this case, what we must do is calculate the price per ounce and the one with the best value is the best purchase:

option 1: a pack of four 6.5-ounce containers of ice cream for $ 3.77

3.77 / (4 * 6.5) = 0.145

option 2: a pack of three 8-ounce containers for $ 3.87

3.87 / (3 * 8) = 0.161

The value of the price per ounce is less in option 1, therefore, this is a better purchase

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
