Teresa has to buy school supplies for her 4 children, and wants to estimate the total cost of the school supplies. she knows that:
each child needs a backpack, a binder, 6 spirals, and 4 pens.
the most expensive backpack is $54.00 dollars.
the least expensive backpack is $32.00 dollars.
the binders cost $3.00 each.
the spirals cost $1.66 for three.
the pens cost $0.40 each.
there is 8% sales tax on her total purchase.
estimate how much money the school supplies will cost.
a.
$440.00
b.
$220.00
c.
$408.00
d.
$55.00

10000

step-by-step explanation: divide by 2,

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)

add a pic of the graph, then ill edit this "answer" and solve it for you : 3
