Amath test is worth 100 points and has 30 problems. each problem is worth either 3 points or 4 points. how many 4- point problems are there?

Ten

Step-by-step explanation:

The harder part is to make an equation out of the text.

Let x be the number of 3 point questions.

In this case the nu,ber of 4 point questions is (30-x)

They all add up to 100 points.

3x + 4(30-x) =100

Solve for x

x=20

There are 20 three point questions

30-20=10 There are ten four point questions.

Lets check.  20*3 + 10*4 = 60+40=100

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
