Jane has $350 to spend while she is on vacation. She decides to spend $50 a day. Which equation gives the amount, a, Jane has left to spend after d days on vacation?

D) a = 350 - 50d

Answer: The required equation is,

a = 350 - 50 d

Step-by-step explanation:

Here, d represents the number of days and a represents the amount left after d days,

Given,

The initial amount she has = $ 350,

Also, the amount she spend in each day = $ 50,

So, the amount she spend in d days = 50d dollars,

Thus, the amount left after d days = Initial amount - Amount spent in d days

⇒ a = 350 - 50d,

Which is the required equation.
