Set up a proportion:
y = 35 when x = 7
y = ? when x = 10
To get x from 7 to 10, you have to multiply by 
. Therefore, you do the same to 35, and you get:
And your answer is 50 :)
All I know is that question 1 is B and I think for question 3 is Sammy is correct.
The answer is the first one or -10
Answer:
I think it is 350(1.2)^t because you take the starting amount (350) and then multiple it by the growth rate (which is 20%, but when added to 100 and the put into a decimal is 1.2) raised by the number of hours (t).
I hope this helps.
