6% tax means 6% of $3.50
Convert 6% to decimal (move decimal 2 spots to the left): 6% ⇒ .06
Multiply 3.50 with .06 = .21 <-- That's .21 cents of 3.50
That means you have to pay an extra 21 cents. Add that to the $3.50 you had to pay.
$3.50 + $0.21 = $3.71 <-- Price after tax
Answer:
x + 4y = 4
4y = 4 - x
multiply both sides by 1/4
y = 1/4( 4- x)
y = 1- 1/4x

Step-by-step explanation:
Henry is making a corn grits recipe that calls for 1/4 cup of corn grits for every 1/2 cup of water. How much water will he need if he uses 1 1/2 cups of corn grits?
Expand 1/2 to 2/4, if there is 1 1/2 cups of corn grits, that means that 1/4 cups of corn grits was used 6 times, 1/2x6=3. He will need 3 cups of water
Answer:
Step-by-step explanation:
I don't know if we are supposed to use the numbers from the previous problem. If not, then what ever number you choose will be 7 times the size of the protein. So let's assume that the givens follow question 2.
The amount of protein = x
The amount of carbs = (700/100)*x
proteins + carbs = 100%
x + 7x = 100 Combine the left
8x = 100 Divide by 8
8x/8 = 100/8
x = 12.5
Protein = 12.5 carbs
Carbs = 7*12.5 = 87.5 grams
So both cereals contain 12.5 grams of proteins and 87.5 grams of carbs.
