Market Basket sells chocolate chip cookies . A-Best cookies are 12 cookies for $6.00. A- Okay cookies sell 20 cookies for $ 8.00
agasfer [191]

The unit price for best cookies is $0.5

The unit price for Okay cookies is $0.4

Step-by-step explanation:

The unit cost is obtained by dividing the total cost by the quantity

Given

<u>Best Cookies:</u>

Cost = $6.00

Quantity = 12

So the unit price will be:

Unit\ price\ for\ best\ cookies = \frac{6}{12}\\=0.5\ dollars\ or\ 50\ cents

<u>Okay Cookies:</u>

Cost = $8.00

Quantity = 20

The unit price is:

Unit\ price\ of\ okay\ cookies = \frac{8}{20}\\= 0.4 \dollars\ or\ 40\ cents

The unit price for best cookies is $0.5

The unit price for Okay cookies is $0.4

Keywords: Unit price, division

Harlamova29_29 [7]

Answer:

60 muffins

Step-by-step explanation:

Find out how much ml you need for each ingredient.

20 muffins =

220 ÷ 20 = 11 (milk)

250 ÷ 20 = 12.5 (castel sugar)

400 ÷ 20 = 20 (flour)

Find out the greatest number of muffins Jack can make.

1 litre = 1000 ml

1000 ÷ 11 = 90.90 (recurring decimal) (milk)

750 ÷ 12.5 = 60 (castel sugar)

1500 ÷ 20 = 75 (flour)

Find the smallest answer out of the 3 questions.

Maureen is taking an antibiotic. The table below shows the amount of antibiotic f(t), in mg, that was present in her body after
MariettaO [177]
One way to test this is by using the equation for Ken on Maureen. Let's say in the first hour,

f(t) = 200(0.976)^1 = 195.2 mg

In the second hour,

f(t) = 200(0.976)^2 = 190.52 mg

In the third hour,

f(t) = 200(0.976)^3 = 186 mg

If you compare this with Maureen's data which is 150, 90 and 54 for the first, second and third hour, respectively, you will see that Maureen's rate is much faster. However, you cannot tell by what factor because the function is exponential, not a multiple. There is no constant difference between their rates. Therefore, we only know that Maureen's rate is much faster.

The answer is <span>Maureen's body eliminated the antibiotic faster than Ken's body.</span>
