the bill for a pizza was 14.50 . Charles paid for 3/5 of the bill. Show two ways to find how much he paid

Answers

Charles paid $8.70 of the bill.

The first way we can find this is:

= Proportion that Charles paid for x Cost of pizza

= 3/5 x 14.50

= 43.5 / 5

= $8.70

The second way is:

= Cost of Pizza - Proportion that others paid for

= 14.50 - ( (1 - 3/5) x 14.50)

= 14.50 - ( 2/5 x 14.50)

= 14.50 - 5.80

= $8.70

In conclusion, Charles paid $8.70 out of the total bill for the pizza.

Well, if the pizza total was $14.50 and if there were 5 people in total, you'd do 14.50 divided by 5 to get $2.09 per person. If Charles paid 3/5 then do 2.09 times 3 to get $6.27.

Janice needs to purchase a new uniform for a job she just accepted. The store indicates that she may have a 30% discount, but that she will need to pay the 8% sales tax on the uniform. If the uniform lists at retail cost of (c), which of the following choices would Janice use to correctly calculate her total cost (T) of the uniform?A. (T) = (c) – 0.3c + 0.08c
B. (T) = 0.7c + 0.08(0.7c)
C. (T) = 0.7 (0.3c + 0.08c)
D. (T) = 0.7 (c – 0.08c)

Answers

I'm not sure I I think its C let me know if its right

Final answer:

The correct formula to calculate Janice's total cost of the uniform is (T) = 0.7c + 0.08(0.7c), as stated in choice B.

Explanation:

To calculate Janice's total cost of the uniform, we need to take into account the 30% discount and the 8% sales tax. The correct formula to calculate the total cost (T) is (T) = 0.7c + 0.08(0.7c), which corresponds to choice B.

You have $6000 to invest in two stock funds. The first fund pays 5% annual interest and the second account pays 9% annual interest. If after a year you have made $380 in interest, how much money did you invest in each account

Answers

Answer:

First fund: $4000

second account: $2000

Step-by-step explanation:

invest x for first fund (A) and y for second fund (B)

interest for A: x * 0.05

interest for B: y * 0.09

0.05 x + 0.09 y = 380 ....(1)

x + y = 6000 ..... (2)

y = 6000 - x ....substitute y in (1)

0.05 x + 0.09 (6000 - x) = 380

0.05x + 540 - 0.09x = 380

0.04 x = 160

x = 4000

y = 6000 -4000 = 2000

check: 4000 x 0.05 + 2000 x 0.09 = 200 + 180 = 380

A building has a shadow that is 25 feet long. A person 6 feet tall cast a similar shadow. How long is the person's shadow? How do you figure out these types of problems?

Answers

Imagine the side of the building is one side to a triangle and the second would be from the top of the building to the point where the shadow ends and the third is from the base of the building to the point where the shadow ends. Just use the pythagoreon theorem to find stuff. I can't solve the problem you gave because you would need the height of the building

The answer is in the question. If it is a similar shadow wouldn't it be the same?
25 feet

You can solve these word problems using ratios and proportions.
