Okay well the starting is 28 dollars, right. But since there is a 20 percent discount, you have to turn 20% to a decimal. That means moving the decimal sign twice to the left to make it .20. From the it would be .20*28, that should equal 5.6. Now, that 5.6 is the amount you have to take away, it is the price of the sale. From then, you subtract which is 28-5.6 which should be 22.4. From that 22.4 you now take away two dollars and then it should be 22.4-2 which should be 20.4. Now that is your answer, 20.4.

Answer:
729 people chosen
Step-by-step explanation:
4 calculations in head when 3^2 = 9
3 calculations in head when 3^3 = 27
2 calculations in head when 3^4 = 81
1 calculations in head when 3^5 = 243
Answer found 3^6 = 729.
3 = 1st = 3^1
9 = 2nd = 3^2 3(3)
27 = 3rd = 3^3 9(3)
81 = 4th = 3^4 27(3)
243 = 5th = 3^5 81(3)
729 = 6th = 3^6 243(3)
Answer:
the production of milk at the Dancing Dairy Farm is increasing by 2158 gallons/year
Step-by-step explanation:
Given the data in the question;
Let us represent the number of cows at the farm with x and
each cow produces y gallons of milk
Total mil production will be T.
so
T = x × y
now, differentiating with respect to t
dT/dt = d( xy )/dt
dT/dt = xdy/dt + ydx/dt
given that;
x = 441
y = 1157
dx/dt = -13
dy/dt = 39
so we substitute
dT/dt = ( 441 )( 39 ) + ( 1157 )( -13 )
dT/dt = 17199 - 15041
dt/dT = 2158
Therefore, the production of milk at the Dancing Dairy Farm is increasing by 2158 gallons/year
