Planning A Party
Planning The 7th Grade End of The Year Party
The point of intersection is (55, 570). I found this out by making the equations equal to each other. I subtracted 9.25x from 10x and got .75x. Then I subtracted 20 from 61.25 and got 41.25. I divided 41.25 by .75 and got 55. I checked my answer by filling in 55 with the equations.
For Burger Bonanza, 98 kids would be able to come to the party. With Pizza Palace 101 kids would be able to come. You would not be able to have decimal or fraction as one of your answers because you can't have a fraction of a person. Even though its money you still can't have half a person come and eat the food.
The point of intersection is (4,300). I got this by making the equations equal to each other. I subtracted 54x from 75x and got 21x. Then I divided 84 by 21 and got 4. I checked my answer by filling 4 into the equations.
For Hoppin Around, we could have the bounce house for 10 hrs. We could have the bounce for 12 hours if we had Jumpin Jacks. There could be a decimal or fraction for my answer because, instead of having people, its time and money. You can split up time and money without leaving any behind.
