<u>Answer:</u>
t = 6.3 days
<u>Step-by-step explanation:</u>
The amount of initial mass is irrelevant when finding the half-life since the remaining mass is always 1/2 of the initial mass.
Taking on both the sides to get:
t = 6.3 days

STEP 1:
Find percentage. 57 out of 100 is the percentage to multiply by.
57/100= 0.57 (= 57%)
STEP 2:
Multiply percentage by the total gallons ordered (24).
=24 gallons * 0.57
=13.68 gallons
ALTERNATIVE METHOD (use which works best for you)
Set up a proportion. 57 to 100 is x out of 24 gallons.
x= number skim gallons to order
57/100= x/24
cross multiply
(57*24)= (100*x)
1368= 100x
divide both sides by 100
13.68 gallons= x
ANSWER: Since you cannot order a partial gallon of milk, round up to 14 whole gallons

Solve in the same way you would solve a normal equation
x/5 - 3 < 5
Add 3 to both sides :
x/5 < 8
Multiply both sides by 5:
x < 40
