Answer:
C
Step-by-step 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:)

Question 1: you would divide 13 from both sides of the equation, making the answer w = 3
Question 2 : you would divide 11 from both sides of the equation, making the answer x = 5
Question 3: the answer is already there, it's r = 5
Answer:
80 units.
Step-by-step explanation:
The rectangle ABCD is drawn and attached in the image below. The diagonal BD measures 100 units, the side BC measures 60 units. We need to find the measure of side DC which is represented by x in the figure.
Note that a Right Angled Triangle DCB is being formed with BD as the hypotenuse and sides BC and DC as its two legs. The Pythagoras Theorem relates the length of hypotenuse and the two legs of the Right Angled Triangle as:
c is the length of hypotenuse = 100
a is the length of one leg = 60
b is the length of second leg = x
Using these values, we get:
Therefore, measure of the side DC is 80 units
