On Fridays at the ballpark, a cup of soda costs $3, and each refill costs $0.70. If x represents the number of refills, which of the following equations represents the amount a person spends on soda?

Respuesta :

The answer is .... 3+.70x
Y=3+.7x. The person pays $3 for the original drink and $.70 for each refill. So .7x is added to the $3 for each refill wit x=the number of refills
