Answer:
9633 plums total
Explanation:
Recall that 240 percent is equivalent to the multiplier 2.4.
Thus, Peter picked 2.4 times as many plums as Roger.
Representing the number of plums picked by each person as p and r,
p = 2.4r
But p = 6800, and so: 6800 = 2.4r, meaning that r = 2833 1/3 plums. No one really picks 1/3 of a plum, so we could round this down to 2833 plums.
Thus, the total number of plums picked by both boys together is:
r + p = 2833 + 6800 = 9633 plums total
