Answer:
42
Step-by-step explanation:
The correct choice is marked.
If you follow instructions, you will compute the quotient for each value in the set:
2520 ÷ 30 = 84
2520 ÷ 42 = 60 . . . . . the value we're looking for (we need go no further)
2520 ÷ 84 = 30
__
The easier way to solve the problem is to multiply the equation by x/60, so you have ...
2520 ÷ 60 = x
Then, you're doing one division instead of two or three.
2520 ÷ 60 = 42 = x
