If peter picked 240 percent more plums than roger picked and if peter picked 6800 plums,
how many did both boys pick altogether?

9633 plums total

Step-by-step 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
