Answer:

20

Step-by-step explanation:

First, let's find how much she spent on the expensive calculators

40 times $16400= $656,000

Now, lets find how much money she had for the cheap calculators.

$774,000- $656,000=$118000

Now that we have her budget (money remaining) for the cheaper calculators, lets divide that by the price for each individual calculator.

$118000/$5900=20

we know that

1) Marika paid 80\% of the purchase price of the house with a loan

2) Marika paid the remaining \$49,400 of the purchase price with her savings

3) \$49,400 represent the 20\% of the purchase price

so

0.20x=49,400

Solve for x

Divide by 0.20 both sides

0.20x/0.20=49,400/0.20

x=247,000

therefore

<u>the answer is</u>

the purchase price of the house is \$247,000
