Kenny plans to paint the mailbox below. If it costs $3.50 per quart of paint and one quart will cover 10 square feet, how many quarts will Kenny need to buy? What will it cost?

If the mail box has about 30 square feet of paint to complete mail box. He would require to pay $10.5.

Step-by-step explanation:

Let use algebra to solve this purpose lets y be the cost of paint. let x be the the square feet to cover the mailbox.Let 3.50 be the cost of the quart of the point for 10 square feet.The formula would be y=3.50*xIf the 10 square feet of $3.50 per quart.if the mailbox is about 30 square feet then y = 3.50 * 3.The result is $10.5 to pay.Algebra is the most important learning to understand mathematics.It is efficient and reality of life to understand any business.Data scientist use linear algebra to start with data analytics.

If you need an equation, it would be y=2x+8, y would be how long it grew, x being weeks.if you need how long he was asleep, it would be 4 weeks if he started with no beard, the equation would be x=8÷2if he did have a beard before hand, the equation would be 2w+x=8
