There will be 45 adults going to the museum. There will be twice as many students as adults. Adult tickets cost $25 each. Student tickets cost $12 each.
How would you represent this question using a tape diagram?
2205
74
No idea what a "tape diagram" is, but the question is easy to solve in the traditional way:
number of adults ---- 45
number of students ---- 90
Just noticed that there is NO question in your post.
If you want the return for the museum
Return = 25(45) + 12(90)
= $2205
