Mrs. Ecker's class is raising money to go on a class trip this spring. They are planning to take a bus to New York City and see all of the sites while they are there. So far, they have $200.00. Two children will not be able to go on the trip because their parents did not give permission. If the class needs a total of $600.00 to go on the trip, how many $2.00 boxes of cookies must they sell?

How much money do they need? How much money do they have already?

THEY HAVE 200.00 DOLLARS AND THEY NEED 400.00

OpenStudy (mathstudent55):

Correct. They need $400 more. Think of the $400 they need to raise. Now they sell boxes of cookies for $2 each. How many $2 boxes of cookies do they need to sell to equal $400?

OpenStudy (anonymous):

would it be 200

Correct, since $400/$2 = 200 400 dollars divided by $2 per box equals 200 boxes.
