If 1 pound of mesquite-smoked, deli-sliced turkey breast cost $7.98 at the second-largest grocery store in town, and each slide is about 1 ounce, what is the cost of 5 slices?

$2.49

Step-by-step explanation:

$7.98 ÷ 16oz = $.49875 per slice

$.49875 * 5 slices = $2.49375

linear

Simplifying

3x + y = 84

Solving

3x + y = 84

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-1y' to each side of the equation.

3x + y + -1y = 84 + -1y

Combine like terms: y + -1y = 0

3x + 0 = 84 + -1y

3x = 84 + -1y

Divide each side by '3'.

x = 28 + -0.3333333333y

Simplifying

x = 28 + -0.3333333333y
