The temperature was 30 degrees. The temperature dropped 50 degrees. Then the temperature increased 5 degrees. What is the temperature now?

-15 degrees

Step-by-step explanation:

In order to get what I answered you first subtract 50 from 30 then you get -20 then it says the temperature increased by 5 so you add 5 to -20 and get -15. Also I don't know if it is in celcius or Fahrenheit but if that's all its asking then it should be right.

i dont know men

step-by-step explanation:

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
