To determine if Sarah has enough yarn to glue onto all 25 picture frames, we can calculate the total amount of yarn needed and compare it to the amount she has.
-
Calculate the total amount of yarn needed: Sarah needs 40 inches of yarn for each picture frame and there are 25 picture frames. \[ \text{Total yarn needed} = \text{Yarn per frame} \times \text{Number of frames} = 40 , \text{inches} \times 25 = 1000 , \text{inches} \]
-
Compare to the yarn Sarah has: Sarah has a total of 950 inches of yarn.
-
Conclusion: She needs 1000 inches of yarn, but she only has 950 inches.
Therefore, Sarah does not have enough yarn to glue onto all 25 picture frames. She is short by: \[ 1000 , \text{inches} - 950 , \text{inches} = 50 , \text{inches} \]
Final Answer: Sarah does not have enough yarn; she is short by 50 inches.
