Answer:
y = 7x+100
Step-by-step 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)
Slope = 1
Slope = change in y/change in x
= (8-5)/(5-2)
=3/3
<em><u>62.5% in 2 equivalent forms can be 0.625 and also 62.5/100.</u></em> For getting a decimal, move the decimal 2 places to the left. For getting a fraction, just put the percent out of 100.
Hope it helps :)
