Question

It is $100 to rent a room at johnnys jumpy party pace and it i $7 extra per child for pizza,drink, and a party bag. write the equation in slope intercept form for the situation above

Answer 1

y = 7x+100

Explanation:

The total cost is the cost of the room plus the cost per child times the number of children

Let x be the number of children and y be the total cost

It costs 100 to rent the room and 7 dollars per child

y = 100 +7x

Rearranging to be in slope intercept form (y=mx+b)

y = 7x+100
