9514 1404 393

Answer:

  1/3; geometric

Step-by-step explanation:

Apparently, your sequence is ...

  81, 27, 9, 3, 1, ...

The differences between these numbers vary, but the ratio of each to the one before is a constant:

  27/81 = 9/27 = 3/9 = 1/3

The sequence is geometric with a common ratio of 1/3. The next number in the sequence is (1)(1/3) = 1/3.

Fiona is pricing two bicycles one is 175 with 10% and the other is 225 with 35% off which bicycle can she afford if she has 150
Gekata [30.6K]
If the one for $175 is 10% off, that means Fiana pays 90% of the price

175 * 0.9 = $157.50

It is too expensive because 157.50 is more than the 150 Fiana has.

The second bike for $225 is 35% off which means Fiana pays 65% of the price.

225 * 0.65 = $146.25

She CAN afford the bike for $225
