Answer:
B
Step-by-step explanation:
if you move the decimal over one you get 15 20 25. If you divide all of them by 5 you get 3 4 5. which is a right triangle.
If it is 2.25 yards per dress, and 4.15 a yard, multiply 2.25 by 4.15 and you get 9.3375 or just 9.34. if there are 4 girls, multiply 9.34 by 4 and you get $39.76
5.50(n) would be an expression to represent the amount he earns.
