The answer is- C. 10 minus 4
A)40% 0f 140 = (4/10)*140=56
b) dicount=12.5% 0f 240 = (12.5/100)*240=30
so, u pay (240-30)= 210
1 quart = 32 fluid ounces
16 is half of 32 so 1 quart fills 2 mugs meaning that she needs 6 quarts of coffee
Finally figured it out :D
The function rules is:
y = -5x - 1
9 = -5(-2) - 1
4 = -5(-1) - 1
-1 = -5(0) - 1
-6 = -5(1) - 1
-11 = -5(2) - 1
