A store buys a video game for the wholesale price of $39.99. The markup on the game is 70%. If sales tax is 8% then how much mon

Answer:The amount of money that you would need to buy the game is $73.324

Step-by-step explanation:

The store buys a video game for the wholesale price of $39.99. There was a markup of 70% on the price of the game. The value of the markup would be

70/100× 39.99 = 0.7×39.99 = $27.993

Cost of the game plus 70% markup would be

39.99 + 27.993 = $67.893

There is sales tax of 8% on the game. This means that the value of the tax would be

8/100 × 67.893 = 0.08 × 67.893 = $5.431

The amount of money that you would need to buy the game would be

67.893 + 5.431 = $73.324

Valentin [98]

Answer:

1. $2r+1.6b=10$

2. $r=5-0.8b$

3. $b=6.25-1.25r$

Step-by-step explanation:

<h3> The complete exercise is: "Brown rice costs $2 per pound, and beans cost $1.60 per pound. Lin has $10 to spend on these items to make a large meal of beans and rice for a potluck dinner. Let b be the number of pounds of beans Lin buys and r be the number of pounds of rice she buys when she spends all her money on this meal.</h3><h3>1. Write an equation relating the two variables.</h3><h3>2. Rearrange the equation so "b" is the independent variable.</h3><h3>3. Rearrange the equation so "r" is the independent variable."</h3><h3 />

1. According to the information exercise given in the exercise, the cost per pounds of brown rice is $2. Since "r" represents the number of pounds of rice Lin buys, the total cost of the brown rice she buys can be represented with this expression:

$2r$
