Chandra bought twice as many plants as Marvin. Kira bought 1/3 as many plants as Chandra. Marvin bought 6 plants. Write an expression that shows the total number of plants purchased. Who bought the most plants?

Chandra bought the most plants

Step-by-step explanation:

We have three persons buying different number of plants.

Chandra bought twice as many as Marvin. Since Marvin bought 6 plants, this mean Chandra bought 6 * 2 = 12 plants

Kira bought 1/3 of what Chandra bought, that means she bought 1/3 * 12 = 4 plants

Expression for the total number of plants purchased is : total number of plants purchased = 4 + 12 + 6 = 22 plants

Chandra bought 6 so she bought the most plants
