When it was 70 degrees outside, 50 members showed up at the beach club. for each degree temperature rose, another 10 members cam
stellarik [79]

Answer:

f(t)=50+10(t-70)

Step-by-step explanation:

Let the outside temperature be t degree.

So, when t=70 degree, number of members, f(t)=50

Now, for every degree rise in temperature, 10 members gets added.

So, when the temperature is t degrees, rise in temperature is (t-70) degrees.

Therefore,

For (t-70) degrees rise, number of members added = 10(t-70)

Hence, total number of members added as a function of temperature is given as the sum of members at t= 70 degrees and for (t-70) degrees rise. This gives,

f(t)=50+10(t-70)
