12.5 / 100 = 20 / X
multiply 100 x 10 to get 2000
multiply 12.5 x X to get 12.5X
divide both 2000 and 12.5X by 12.5 to get 2000 / 12.5 = X
2000 / 12.5 = 160 therefore X = 160
check your answer by multiplying 0.125 by 160 to get 20
Answer:
x = -10
Step-by-step explanation:
x/4=-2.5

x/4*4=-2.5*4
-2.5 times 4 is -10
x = -10

Answer:
B
Step-by-step explanation:
Lets convert everything to gallons.
Alpha Mart:
1 quart = 0.25 gallons
1 * 0.25 = 0.25 gallons for $1
1 / 0.25 = 4 * 1 = $4 per gallon
Beta Mart:
1 gallon for $3
Gamma Mart:
1 pint = 0.125 gallons
0.125 gallons for $0.54
1 / 0.125 = 8 * 0.54 = $4.32 per gallon
Delta Mart:
1 quart = 0.25 gallons
2 * 0.25 = 0.5 gallons for $1.86
1 / 0.5 = 2 * 1.86 = $3.72 per gallon.
As we can see from all the unit prices, Beta Mart sells milk for the cheapest price.
Best of Luck!
