Question

Last week Tiffany practiced her bassoon a total of 7 hours. This was 2 hours more than she practiced the previous week. How many hours did Tiffany practice the previous week?

Answer 1

Tiffany practiced the bassoon for 5 hours on the previous week.

Answer 2

Tiffany practiced 5 hours in previous week to the last week.

Given that:

• Tiffany practiced her bassoon last week a total of 7 hours.

• Her practice last week was 2 hours more than her time of practice in previous week.

To find: How many hours did Tiffany practice the previous week?

Equation formation and calculation:

Duration of practice in last week = 2 hours + Duration of practice in previous week

x = 2 + y,

where x = Duration of last week = 7 hours

and y =Duration of practice in previous week

Thus, we have:

$x = 2 + y\\7 = 2 + y\\y = 7 - 2\\y = 5$

Thus, y = Duration of practice in previous week = 5 hours.

Thus, Tiffany practiced 5 hours in previous week to the last week.
