Answer:
348 out of 725
Step-by-step explanation:
This is a ratio question, giving us a sample that we can use to extend the number to all students.
12/25 students play a sport so we want the value of x in x/725
So:
12/25 = x/725
Cross-Multiply:
25x = 8700
Divide by 25 to get x:
348
You can also check by dividing these ratios to see if you get the same number. In this case, you do (.48).
YES
because they are all different lengths
Angelo is 66 Brandon is 26 Carl is 31
Variables a=Angelo b=Brandon c=Carl
Equation (1/3)(a+b+c) = 41
cost = 32
price = not sure
