Question

Nick is given $50 on a vacation. He decides to spend $5 a day. Write an equation relating to the amount of money Nick has left, y, and the number of days, x, Nick spends money

Answer 1

y = -5x + 50

Explanation:

We'll write the equation in y = mx + b form, where b is the original amount of money (50), and m is the amount of money he spends he each day(5). Since he's spending 5 dollars, that means that 5 dollars is being lost everyday, so m will be -5:

y = -5x + 50

Hope this helps :)
