The function s(t, r)=70(t−90)(4−r) gives an ice cream shop's daily sales as a function of temperature t (in degrees°f) and rain r (in inches). find sr (80, 6) (include the appropriate units) and explain what it means.

The value of Sr (80, 6) is 1400 units.

The shop's daily sales when temperature is 80°F and rain is 6 inches.

Step-by-step explanation:

Given function that represents the daily sale,

S(T,r)=70(T−90)(4−r),

Where,

T = temperature (in degrees°F),

r = rain ( in inches),

If T = 80°F, r = 6 inches,

S(80, 6) = 70(80−90)(4−6) = 70(-10)(-2) = 1400 units

Hence, S(80, 6) represents the shop's daily sales when temperature is 80°F and rain is 6 inches.
