Answer 1

132

Explanation:

Answer 2

$132

Explanation:

[] First, we will set up an equation for Ross.

-> We will use slope-intercept form (see attached)

-> The slope:

`(y_(2) -y_(1))/(x_(2) -x_(1) )` =
`(81-40.5)/(6-3)`=
`(40.5)/(3)`=13.5

-> The y-intercept:

y = 13.5x + b

(81) = 13.5(6) + b

81 = 81 + b

0 = b

-> Final equation:

y = 13.5x

-> For 8 hours, we will plug in 8 as the x.

y= 13.5(8)

y = $108

[] Joey earns 3 dollars more,

y = (13.5 + 3)x

-> Now we will plug 8 into the equation as x,

y = $132
