Im earned $12.50 per hour working as a babysitter. He worked 15 1/2hours during winter break. After getting paid, he put $150 in the bank and spent the rest on comic books. Each comic book cost $2.50. How much money did Tim earn during winter break?

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8

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)

i think the answer is b
