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.
a. Write an inequality to represent this problem. Use y to represent the number of skeins of yarn.
b. What is the most number of skeins Sharon can afford to buy? Justify your answer in two or more complete
sentences.

she can around 9.90 skeins of yarn with the 25 bux

Step-by-step explanation:

So to start lets round $14.99 into $15 and $2.75 to $3 $25 subtract $18 equals to $7. So she can buy about 2 more skeins of yarn

Step-by-step explanation:

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
