A group of 20 tourists pay $160 to go on a swamp tour. If the cost per person stays the same, how much will the tour cost 30 tourists?
Responses
A $240$240
B $200$200
C $180$180
D $220$220
The cost per person is $160/20 = $8.
To find the cost for 30 tourists, we can multiply the cost per person by the number of tourists:
$8 \times 30 = $240
Therefore, the answer is (A) $240.
To find out how much the tour will cost for 30 tourists, you can use the concept of direct variation.
Direct variation means that the cost is directly proportional to the number of tourists. In this case, if 20 tourists pay $160, then the cost per tourist is $160 / 20 = $8.
To find out the cost for 30 tourists, multiply the cost per tourist ($8) by the number of tourists (30):
$8 x 30 = $240.
Therefore, the correct answer is A) $240.
