Question

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.

Answer 1

25 - 14.99 = 10.01

10.01 divided by 2.75 = 3.64.

Sharon can get 3 skeins of yarn for her sister.

Since after the knitting machine, she is only
left with approximately $10 that leaves her able to get 3 skeins of yard with change left over. Since 3 skeins would cost 8.25, that would only leave Sharon with $1.75. Which would not be enough to buy another skein

Answer 2

$25 >= 14.99+2.75x
