Answer:
D. 3.35
Step-by-step explanation:
First we need to form an equation and solve it to find the number of weeks when the prices were the same. Because the prices were the same we can say that b = c, and therefore form the equation:
2.35 + 0.25x = 1.75 + 0.4x - Now we nee to solve it and find x.
2.35 - 1.75 = 0.4x - 0.25x
0.6 = 0.15x
x = 0.6 ÷ 0.15
x = 4 weeks
So now we substitute x into the equation for beef and find the price.
b = 2.35 + (0.25 × 4)
b = 2.35 + 1
b = $3.35 per pound

Answer:
The number of the cups of uncooked rice is 3 cups
The number of the cups of water is
cups
Step-by-step explanation:
* Let us read the recipe of Nasi Gorang
- 2 cups of uncooked rice need
cups of water to
make
cups of cooked rice
- Joseph needs
cups of cooked rice
- We need to know how many cups of uncooked rice Joshep needs
for this recipe and how much water should be added
* We can solve this problem by using the ratio method
⇒ uncooked cups : water cups : cooked cups
⇒ 2 :
: 
⇒ x : y : 
- By using cross multiplication
∵ x (
) = 2 (
)
∵
= 
∵
= 
∴ x (
) = 2 (
)
∴
x = 13
- Divide both sides by 
∴ x = 3
∴ The number of the cups of uncooked rice is 3 cups
- By using cross multiplication
∵ y (
) = (
)(
)
∵
= 
∵
= 
∵
= 
∴
y = (
)(
)
∴
y =
- Divide both sides by 
∴ y = 
∴ The number of the cups of water is
cups
