Question

(System of inequality word problem.)

Frankie is saving his money to buy the new Nintendo Switch. The switch is on sale for $300. He already has $215 saved up and his mother tells him she will pay him $7 for each extra chore he completes around the house. What is the minimum number of chores he must complete to have enough money for the Switch?

A. 12 chores
B. 14 chores
C. 13 chores
D. 11 chores

Answer 1

C

Explanation:

Because nintendo price=300$

He has 215$

1 chore he does=7$

Meaning if he did 10 chores he get's 70$ added so he did 10 now he has 285$ If he does 2 more chores that is 14$ more added.

So he now has 299$ so he done 12 chores and he needs 1 more dollar so if he did 1 more he gets 306$ and that was the least amount of chores he could do if he wanted 300$

And there's your answer

Hope this helps have a awesome day:)
