Ray wants to buy an item worth $500. Which option is the most cost-effective?

LuckyWell [14K]

Ray wants to buy an item worth 500$ in the most cost-effective way. Let's study each of the 3 cases and see with option is the best.

In the first option, he'll buy the item at list price with a coupon for $10 off. So he'll buy it at 500-10 =$490.

In the second option, he'll buy a membership for $35 and then get the item at a 15% discount. With a 15% discount, the price of the item will be 500 - (500*0.15) = 500 - 75 = $425. And with the membership price, he'll pay a total of 425 + 35 = $460.

The third option is to buy the item online at a 10% discount and pay $4 for the shipping. At 10% discount, the price of the item will be 500 - (500*0.1) = 500 - 50 = $450. And with cost of the shipping, he'll pay a total of 450+4 = $454.

So if he chooses the first option, he'll pay $490. With the second, he'll pay $460. And finally with the third, he'll pay $454.

So the third option is the most cost-effective, buying the item at $454.

Hope this helps! :)

Assume that MTA Sandwiches sells sandwiches for $2.85 each. The cost of each sandwich follows:

mixas84 [53]

Answer:

a. profit is lower

b. lowest price $2.29

Step-by-step explanation:

a. We have to analyze how this especial order affect the profit of the company

Profit = Revenue- Total cost = P(x) =(Px * Q)-(FC + vc*Q)

Regular production profit= $2.85 x 18,400 units -$2.60 x 18,400 units=

Regular production profit=4600

Production with special order= (P1 * Q1)+(P2 * Q2)-(FC + vc*Q)

P2= price of special order

Q2= quantity of special order

Q= Q1 +Q2

Production with special order= (P1 * Q1)+(P2 * Q2)-(FC + vc*Q)= $2.85 x 18,400 units +$1.85 x 800 units - $18,400- $1.60 x 19600=

Production with special order= 51888 +1480- $18,400- 30720

Production with special order= 4.248‬

b.Production with special order= (P1 * Q1)+(P2 * Q2)-(FC + vc*Q) =4600

=51888 +(P2 * 800)- $18,400- 30720 =4600

=(P2 * 800)= 4600- 51888 + $18,400+30720

P2=1.832/800 = 2,29

Which of the following properties completes the proof?

Tresset [83]

The subtraction property of inequality can be used to proof that x = 7 from x + 8 = 15

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

Given that x + 8 = 15

Hence:

x + 8 - 8 = 15 - 8 (subtraction property of inequality)

x = 7

The subtraction property of inequality can be used to proof that x = 7 from x + 8 = 15

Find an equation of the line parallel to y=2x+3 and that passes through the point (5,3)

timama [110]

Answer:

y = 2x - 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 2x + 3 ← is in slope- intercept form

with slope m = 2

Parallel lines have equal slopes , then

y = 2x + c ← is the partial equation

To find c substitute (5, 3 ) into the partial equation

3 = 10 + c ⇒ c = 3 - 10 = - 7

y = 2x - 7 ← equation of parallel line
