London bought a tray of plants for$8.15. there are 16 plants in the tray . if landon bought 1 plant , about how much would it have cost ?

Divide. The total cost is $8.15. That's your numerator. There are 16 plants. That's your denominator. Divide using long division. Your answer should be around $0.50 a plant.

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
