B i think

Step-by-step explanation: The numbers 79,340 and 210,00 go together. The rest of the numbers go together as well.

D.

Step-by-step explanation:

You can eliminate A because Beth gets a raise of 210 dollars per year. You can also eliminate B because the equal sign indicates how much years will it take for Beth and Robert earn the same amount. So now it leaves C and D. You can eliminate C because 79,340 is added to 210y, so each year, y, the raise will be 210 per year. But C uses 840y, which isn’t right. This leaves D to be the right answer. Hope this helps. If you have any questions or concerns, feel free to comment them below!
