Sofia buys 3.8 pounds of potatoes for $0.85 per pound. Flynn buys 4.2 pounds of potatoes for $0.75 per pound.
Pavlova-9 [17]

Answer:

Step-by-step explanation:

A. $0.08

Step-by-step explanation:

I would find out the total price of potatoes for each person:

Sofia: $0.85 x 3.8lb = $3.23

Flynn: $0.75 x 4.2lb = $3.15

To get the final answer, I would subtract to find the difference between the two prices.

$3.23 - $3.15 = $0.08

If your paper has 128 rectangles, how many folds did you make?
Mila [183]
If you fold a piece of paper, it will have 2 rectangles.
If you fold it again, it will have 4 rectangles.
If you fold it again, it will have 8 rectangles.
So, if you fold it n times, it will have 2^n rectangles.

2^n=128 \\
2^n=2^7 \\
n=7

If your paper has 128 rectangles, you made 7 folds.

A pharmacist is trying to stock the pharmacy with cheaper alternatives for customers. She will stop carrying the more expensive
raketka [301]

Answer : C.  Caplet form is the most expensive.

Tablet form comes in 50 mg tablets and cost $75.00 for a bottle of 100 tablets.

50 mg of 100 tablets so 50 * 100 = 5000mg

5000mg cost = $75.00

So 1mg of tablet form cost = \frac{75}{5000} = 0.015

Capsule form comes in 75 mg capsules and cost $63.75 for a bottle of 85  capsules

75 mg of 85  capsules,  so 75 * 85 = 6375mg

6375mg cost = $63.75

So 1mg of Capsule form cost = \frac{63.75}{6375} = $0.01

Caplet form comes in 100 mg caplets and cost $70.00 for 40 caplets

100 mg of 40 caplets ,  so 100 * 40 = 4000 mg

4000mg cost = $70.00

So 1mg of Caplet form cost = \frac{70}{4000} = $0.0175

Caplet form is the most expensive.
