6. When Landon saves $15 more, he will have enough money to buy a basic MP3 player. The player he wants to buy costs $199, which is 4 times the cost of the basic player. Which equation could be used to determine n, the number of dollars Landon has already saved?

A. 4n +15 = 199 B. 4(n+15) = 199 C. n + 4(15) = 199

Answers

Answer:

A) 4n+15=199

Because n is the cost of the basic player, so 4*n would be the cost of the player he wants. Also +15 since he needs 15 more dollars.

Jess is painting his car. He’s created a purple color that uses red paint and blue paint in a ratio of 6:5. Jess uses 15 pints of blue paint. How many pints of paint does he use in total?

Answers

Since the ratio of red to blue paint is 6 and 5. And 15 pints are blue you do 15 divided by 5 and it is 3. So you would do the same for red and it will be 18 so you do 18 plus 15 which is 33 pints in total
