Abakery offers a sale price of $2.90 for 4 muffins. what is the price per dozen?

8.70

Step-by-step explanation:

3 * 4 = 12.

12 = 1 dozen

So you have to multiply 2.90 * 3

The answer is 8.70

That's one way to do the problem. Here's another.

4 muffins = $2.90

12 muffins = x                Cross multiply.

4x = 12*2.90

4x = 34.80                     Divide by 4

4x/4 = 34.80/4              Do the division

x = $8.70

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
