Blueface is going to open up for Kodak Black's next concert on the Gulf Coast! Amar is trying to make some money by selling Blueface and Kodak Black T-shirts outside the Coliseum. Each Kodak Balck T-shirt sells for $20, and each Blueface T-shirt sells for $15. Amar made 235 dollars and sold 14 T-shirts. How many Kodak Black shirts did he sell, and how many Blueface shirts did he sell?

Solution:

Let "x" be the number of Kodak Black shirts sold

Let "y" be the number of Blueface shirts sold

Cost of each Kodak Balck T-shirt = $ 20

Cost of each Blueface T-shirt = $ 15

Amar made 235 dollars and sold 14 T-shirts

Therefore,

x + y = 14 ------- eqn 1

Given he made 235 dollars

Therefore,

Solve eqn 1 and eqn 2

Multiply eqn 1 by -20

-20x - 20y = -280 ------ eqn 3

Add eqn 2 and eqn 3

20x + 15y = 235

-20x - 20y = -280

( + ) ----------------------

-5y = -45

y = 9

Substitute y = 9 in eqn 1

x + 9 = 14

x = 14 - 9

x = 5

Thus he sold 5 Kodak Black shirts and 9 Blueface shirts

(-1,-0.5)

step-by-step explanation:

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
