SCRAPBOOK For exercise 56-58, use the following information.

Ian has $6.00, and he wants to buy paper for his scrapbook. A sheet of printed paper costs 30垄, and a sheet of solid color paper costs 15垄.

56. Write an inequality that describes this situation.

Short Answer

Expert verified

The inequality that describes this situation is 0.3x+0.15y鈮�6.

Step by step solution

01

- Convert cents to dollar

1 dollar is equal to 100 cents, therefore, 30垄 will be equal to 0.3$ and similarly, 15垄 will be equal to 0.15$.

02

- Define the variables

Let Ian buy 鈥榵鈥� sheets of printed paper and 鈥榶鈥� sheets of solid color paper.

Since, 1 sheet of printed paper costs 0.3$, therefore, 鈥榵鈥� sheets of printed paper will cost and similarly, since 1 sheet of solid color paper costs 0.15$, therefore, 鈥榶鈥� sheets of solid color paper will cost 0.15y.

03

- Write the equation

Note that Ian can buy the sheets worth 6$ or less than 6$, but not more than that. Therefore, the inequality will be: 0.3x+0.15y鈮�6.
