Answer:
8x
Step-by-step explanation:
x · 8
8x
Adam pays for 2/5 of the meal so his father pays for 3/5
3/5 = 52.50
1/5 = 52.50 / 3 = 17.50
so cost of the meal = 5 * 17.50 = $87.50
Y=mx+b
They give you the slope - 1/5
y=-1/5x+b
Now plug in the two coordinates of x and y to find b
7=-1/5(-5)+b
7=1+b
b=6
So the answer is y=-1/5x+6
