Two teams are distributing information booklets. Team A distributes 60% more boxes of booklets than Team B, but each box of Team

Alexxx [7]

Answer:

C. 4,100

Step-by-step explanation:

"60% more" is represented by a multiplier of 1 + 0.60 = 1.60.

"60% fewer" is represented by a multiplier of 1 - 0.60 = 0.40.

Let b represent the number of booklets distributed by Team B. Then the number distributed by Team A is ...

1.60 × (0.40b) . . . . 60% more boxes, each with 60% fewer booklets

= 0.64b

Then the total distributed by both teams is ...

b + 0.64b = 1.64b = (164/100)b = (41/25)b

The only answer choice that is a multiple of 41 is ...

4,100 . . . choice C

For 4100 to be the number of booklets distributed by both teams, Team B will have distributed 2500 booklets, and Team A will have distributed 1600 booklets. Team A might have distributed 160 boxes of 100 booklets, while Team B might have distributed 100 boxes of 250 booklets.
