i need help on my math

Question

i need help it says find the independent and dependent variable wand the questions are

1. A pizza cost $10, plus an additional fee per topping.
2. a contestant on a game show receives $100 per correct answer.
3. it takes a catering company 10 min to make a meal.

Answer 1

Independent variables are what you control, dependent ones are the result of those decisions.

You choose the number of toppings, and the price is the result. The contestant gives right answers and their prize money changes. The caterers decide how many meals to make and the time is a multiple of that number.
