The difference between two numbers is 28. The larger number is 8 less than twice the smaller

1 answer:

3 0

X - y = 28 (difference between the two numbers)
and
x - 8 = 2y (8 less than twice the smaller number)

From the first . . . x = 28 + y

28 + y - 8 = 2y
20 = 2y - y
20 = y

x - 20 = 28
x = 28 + 20 = 48

Answer: Bruno = 16 cans, Blaze = 14 cans

<u>Step-by-step explanation:</u>

Part A gave you the three equations.

Part B showed you the intersected points --> (16, 14), (20, 10), & (21.4, 10.7)

Part C is giving you the Cost function: C(x, y) =0.10x + 0.20y

Input the intersected points into the Cost function to find the maximum.

C(16,14) = 0.10(16) + 0.20(14)

= 1.60 + 2.80

= 4.40

C(20,10) = 0.10(20) + 0.20(10)

= 2.0 + 2.00

= 4.00

C(21.4,10.7) = 0.10(21.4) + 0.20(10.7)

= 2.14 + 2.14

= 4.28

Of the three results we just found, 4.40 is the biggest value.

So, the maximum occurs at C(16,14) = 4.40

Westkost [7]

We know for our problem that Rachel makes $10 per hour. Since $x$ represent the number of hours that she works, $10x$ will be the total amount that she will make for working $x$ hours. We also know that she sells bracelets for $5 each. Since $y$ represents the number of of bracelets that she sells, $5y$ will be her total revenue for selling $y$ bracelets. We also know that she needs to earn at least $200 a week to cover her expenses, so the sum of $10x$ and $5y$ must be equal or greater than 200:

$10x+5 \geq 200$

We can conclude that <span>the graphs that shows the inequality that represents this situation, with its solution region shaded is:</span>
