Answer:
The total amount of paint left is 1.6 gallon of paint remaining
Where she has:
1.5 gallon of orange paint left and 0.1 gallon of black paint left.
Step-by-step explanation:
Step 1
Callie has 2 cans of orange paint with 4.5 gallons in each can.
The total gallons of orange paint that she has is given as:
1 can = 4.5 gallons
2 cans = x gallons
Cross Multiply
x = 4.5 gallons × 2 cans
x = 9 gallons of orange paint.
She also has 9/10 of a gallon of black paint.
Her brother took 0.8 gallon of the black paint
and 3.75 gallons from each of the cans of orange paint.
Since there are 2 cans, the total gallons of orange paint that her brother took = 2 × 3.75 gallons
= 7.5 gallons
Step 2
For orange paint
The amount of orange paint that she has left = 9 gallons - 7.5 gallons
= 1.5 gallons of orange paint left.
For black paint
We are told that: She also has 9/10 of a gallon of black paint.
Converting to decimal
= 0.9 gallon of black paint.
Her brother took 0.8 gallon of the black paint
The total gallon of black paint that she has left =
0.9 gallon - 0.8 gallon
= 0.1 gallon of black paint left.
The total amount of paint Callie has remaining after her brother took the stated amounts is:
1.5 gallon of orange paint + 0.1 gallon of black paint = 1.6 gallon of paint remaining
