Commission or salary: jill has a job offer. she is offered either $50 per day or £30 per day plus a commission of $3 for every plant she sells. how many plants does she need to sell to make the commission offer the best paying option?

7 plants

Step-by-step explanation:

Jill is offered either $50 per day or $30 per day plus a commission of $3 for every plant she sells.

Let she sells the number of  plants = p

30 + (3 × p) > 50

3p > 50 - 30

3p > 20

p > 20/3

p > 6.666 ≈ 7 plants

She need to sell 7 plants to make the commission offer the best paying option.

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)
