The diver's elevation when he is 23% of the way down is -22.356 ft.
thats not an answer
Apologies for the incorrect answer. Given that the treasure is 97.2 feet below the surface and the diver is 23% of the way down, the elevation of the diver would be:
97.2 ft x 0.23 = 22.356 ft below the surface.
So, the diver's elevation would be approximately -22.4 ft.
97.2 ft x 0.23 = 22.356 ft below the surface.
So, the diver's elevation would be approximately -22.4 ft.
not an answer either
Apologies for the confusion. If the diver is 23% of the way down and the treasure is 97.2 feet below the surface, we can calculate the diver's elevation as follows:
23% of 97.2 feet = 0.23 x 97.2 = 22.356 feet
Therefore, the diver's elevation when he is 23% of the way down would be approximately -22.4 feet.
23% of 97.2 feet = 0.23 x 97.2 = 22.356 feet
Therefore, the diver's elevation when he is 23% of the way down would be approximately -22.4 feet.

If the treasure is 97.2 feet below the surface and the diver is 2/3 of the way down, we can calculate the diver's elevation as follows:
2/3 of 97.2 feet = (2/3) x 97.2 = 64.8 feet
Therefore, the diver's elevation when he is 2/3 of the way down would be -64.8 feet.
2/3 of 97.2 feet = (2/3) x 97.2 = 64.8 feet
Therefore, the diver's elevation when he is 2/3 of the way down would be -64.8 feet.

The price of the kayak at the end of four months can be calculated as follows:
Original price: $378
Price reduced by $15 each month for four months: $15 x 4 = $60
Price of the kayak at the end of four months = original price - reduction: $378 - $60 = $318
Therefore, the price of the kayak at the end of four months is $318.
Original price: $378
Price reduced by $15 each month for four months: $15 x 4 = $60
Price of the kayak at the end of four months = original price - reduction: $378 - $60 = $318
Therefore, the price of the kayak at the end of four months is $318.
