Sophia and Jackson are both saving money for college. Sophia has already
saved $700 and plans on saving $60 a week from her part time job as a
waitress. Jackson has not saved any money yet, but he just got a job as a
bank teller and plans on saving $80 week. How long will it take before Sophia
and Jackson have saved the same amount of money?

518,400

step-by-step explanation:

the area is multiplying all the given measurements together.

40 * 18 * 30 * 24 = 518,400

the answer is b

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)
