Kara bought a 15.4 lb turkey and 11.6 lb ham for Thanksgiving and paid $38.51.  Jane bought a 10.2 lb turkey and a 7.3 lb ham and paid $24.84.

For these problems, let x be the cost of turkey per pound, and y be the cost of ham per pound.

1

Write an equation to represent Kara's shopping.

Write the equation in standard form (Ax+By=C), with no spaces or "$".

1

What is the cost of ham per pound?

You will need to write another equation, then find the intersection.

Enter your answer as a number to 2 decimal places, no spaces or "$".

Owen has a collection of nickels and quarters worth $8.10.  If the nickels were quarters and the quarters were nickels, the collection would be worth $17.70.  

For these problems, let x be the number of nickels, and y be the number of quarters.

1

Write an equation to represent the first sentence. Use decimals for the value of each coin.

Write the equation in standard form (Ax+By=C), with no spaces or "$".

1

What is the number of nickels in Owen's collection?

You will need to write another equation, then find the intersection.

Dwight invested $12000 total in stocks and bonds.  The stocks earned 4.8% annual interest, and the bonds earned 7% annual interest.  Together, the total interest earned for one year was $763.  

For these problems, let x be the money invested in stocks, and y be the money invested in bonds.

Remember:  I=PRT
I = interest earned
P = principal investment
R = interest rate, converted from % to decimal
T = time (# of years for annual)

Also remember, to convert a % to a decimal, divide the % by 100.

1

Write an equation representing the total interest earned.

Write the equation in standard form (Ax+By=C), with no spaces, commas or "$".

1

How much did Dwight invest in stocks?

You will need to write another equation, then find the intersection.

Give your answer as a number, no commas, "$" or spaces.
