Your answer is A, you can be a carrier and not have the disorder
1 batch need 3/4 gallon of milk
She has 1/4 gallon cup
(3/4) divided by (1/4)
A technique in math is just flip the divider which is (1/4) to (4/1)
so it becomes (3/4) multiply (4/1) = (3x4) / (4x1) = 12/4 = 3 times for one batch
She needs three batches so 3 x 3 = 9 times to fill the measuring cup to make all 3 batches of milkshake.
Answer:
The cost of one cup of hot chocolate is $4.50
Step-by-step explanation:
Let
x ----> the cost of one cup of hot chocolate
y ----> the cost of one cup of hot tea
we know that
3x+4y=25.50 ------> equation A
y=(2/3)x -----> equation B
Solve the system of equations by substitution
substitute equation B in equation A and solve for x
3x+4(2/3)x=25.50
3x+(8/3)x=25.50
(17/3)x=25.50
x=25.50*3/17
x=$4.50
therefore
The cost of one cup of hot chocolate is $4.50
