Set up and solve an equation for the following business situation.
Pitt's Pit Stop sold $16,003.50 worth of gasoline yesterday. Regular sold for $3.30 a gallon and premium sold for $3.45 a gallon. If the station sold 370 more gallons of regular than premium, answer the
following questions.
(a) How many gallons of each type of gasoline were sold?
regular
gal
premium
gal
(b) If the profit on regular gas is $0.15 per gallon and on premium is $0.18 per gallon, what was the station's total profit (in dollars)?
$

2190 ; 2560 ;

$778.2

Explanation:

Total worth of gasoline sold = 16003.50

Cost of regular = 3.30

Cost of premium = 3.45

Let :

premium Gallon sold = x

Regular gallon sold = 370 + x

Hence, mathematically;

(3.45*x) + (3.30 * (x + 370)) = 16003.50

3.45x + 3.30x + 1221 = 16003.50

6.75x = 16003.50 - 1221

6.75x = 14782.5

x = 14782.5 / 6.75

x = 2190

Premium Gallon sold = 2190 gallons

Regular gallon sold = 2190 + 370 = 2560 gallons

Profit per regular gallon sold = $0.15

Progit per premium Gallon sold = $0.18

Total profit = (2190 * 0.18) + (2560 * 0.15) = $778.2

ans.

heterothermic organisms include those organisms that can switch between homeothermic (having body temperature higher than environment) and poikilothermic (having variation in internal body temperature) strategies.

some migratory birds show heterothermy as they decrease their metabolic rate during cold nights to keep their body temperature low. drop in metabolic rate allows increase in production efficiency of birds that reduces the internal body temperature to make it equal to external cold temperature during cold nights.

thus, the correct answer is 'birds allow their temperature drop in order to increase their production efficiency.'
