Answer:
h= 0.25c +4
Step-by-step explanation:
➀ Define variables
Assuming that you are asking for the equation representing the height of the stack, let's start by letting the height of the stack be h inches and the number of cups be c.
➁ Find the increase in height with every additional cup
If an additional cup is stacked on the first cup, the height increment is 0.25 inches. When 2 cups are added, the height increment is 2(0.25)= 0.5 inches. Thus the expression for the increase in height is 0.25c, where c is the number of cups as we have already defined in step 1.
➂ Find the total height of the stack
Since the height of the first cup remains constant at 4 inches tall, the total height of the stack can be represented by the equation:
h= 0.25c +4
