The serving size for toddler's daily vitamin C is 3/4 cup of orange juice. If there are 2 1/4 cups of orange juice, how many servings of vitamin C are there for a toddler?

Answers

Answer:

3 servings

Step-by-step explanation:

To find the number of servings, we need to determine how many sets of ¾ cups there are in [tex]2 \frac{1}{4} [/tex]cups of orange juice.

[tex]2 \frac{1}{4}[/tex]

[tex] = \frac{2(4) + 1}{4} [/tex]

[tex] = \frac{9}{4} [/tex]

Number of servings

[tex] = \frac{9}{4} \div \frac{3}{4} [/tex]

[tex] = \frac{9}{4} \times \frac{4}{3} [/tex]

[tex] = \frac{9}{3} [/tex]

Stores often mark up items each year to cover inflation. Last year, a CD at Juan’s Tunes cost $12.95. This year, the cost was marked up 8%. The store also gave anyone who bought four CDs this year a 10% discount. Explain the steps to find the final cost for the four CDs this year.

Answers

Answer:Find the amount the store marked up the CDs by.

12.95 * .08 = 1.034 which rounds to 1.04

Add that to the former price.

12.95 + 1.04 = 13.99

Multiply by 4 to see how many 4 CDs cost.

13.99 * 4 = 55.96

Multiply by .1 to see how much the discount is.

55.96 * .1 = 5.596 which rounds to 5.60

Subtract the discount from the original price.

55.96 - 5.6 = 50.36

It costs $50.36 to buy four CDs this year.

Step-by-step explanation: Have a good day Ms. Gurllll

50.36 is the correct answer please mark me as branlilest

+6 +6
4m = 12+10m
divide by 10 both sides
.4m = 12


~another way~
-6+4m = 6+10m
-6 -6
0+4m = 10m
divide by 4 on both sides
2.5m

It begins to decrease at the rate of $ 13.32 each hour. If the two rates continue, in how many hours will the prices of the two stocks be the same?

Answers

Answer:

Let the hours when they equalize=h, then we have:

12.25 + .13h=13 - .09h

.13h + .09h=13 - 12.25

.22h=.75 divide both sides by .22

h=.75/.22

h=3 9/22,  hours, when they will equalize.
