Question

Malik received a$300 gift card from his grandparents and is using it only to pay for his karate lessons, which cost $30 per month.

​Write a function that describes the amount, d, in dollars, on the card after t months in both general and factored form.

Answer 1

(General function) d(t) = 300 - 30t

(Factored version) d(t) = 30(10 - t)

Explanation:

The amount in dollars is represented by d, and the amount of months is represented by the letter t. Using this, you can construct an equation using the given values in the form of f(x) = a - b(c). This equation represents the decrease in Malik's income after one month.

Hope this helps! :)
