Question

On Fridays at the ballpark, a cup of soda costs $3, and each refill costs $0.60. If x represents the number of refills, which of the following equations represents the amount a person spends on soda?

Answer 1

In order to make an equation for the sodas, We first need to look at what we know. We know that a cup of soda initially costs $3. Now we know that our variable x is .60.

We now have to put it into an equation where 3 is a solid term while .60 can change. This then can be represented by:

.60x+3=y 
Y is your total that a person spends on soda. 

Answer 2

Keeping in mind the end goal to make a condition for the soft drinks, We initially need to take a gander at what we know. We realize that a measure of pop at first expenses $3. Presently we realize that our variable x is .60. 
now you need to place it into a condition where 3 is a strong term while .60 can change.

60x+3=y.
Y is your aggregate that a man spends on pop.
