Sharon has at most $25 to spend on her sister's birthday gift. She already bought a knitting machine for her, which cost $14.99. She would also like to get her sister some skeins of yarn to go with it. Each skein costs $2.75. Write an inequality to represent this problem. Use y to represent the number of skeins of yarn. What is the most number of skeins Sharon can afford to buy? Justify your answer in two or more complete sentences.

3

Step-by-step explanation:

Step 1:  Make an inequality

14.99 + 2.75y ≤ 25

Step 2:  Solve for y

14.99 + 2.75y ≤ 25

14.99 + 2.75y - 14.99 ≤ 25 - 14.99

2.75y / 2.75 ≤ 10.01 / 2.75

y ≤ 3.64

 The most skins that she can buy is 3 because she can get 3.64 but she can only get 3 full ones.

2.75y ≤ 10.01; 3 skeins

Step-by-step explanation:

Let y be the number of skeins

Then,

2.75y + 14.99 ≤ 25

2.75y ≤ 10.01

y ≤ 10.01/2.75

y ≤ 3.64

She can afford at max 3 skeins, because number of skeins has to be a whole number

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
