deff fn [24]

Answer:

$68.24

Step-by-step explanation:

Three friends went to Texas Roadhouse for dinner. The total bill was $76.25. They left the server a 20% tip and the Montgomery County tax rate is 9.5%.

Given data

The total bill was $76.25

tip

=20/100*76.25

=0.2*76.25

=15.25

Tax

=9.5/100*76.25

= 0.095*76.25

=$7.24375

In all the bills is 76.25-15.25+7.24375

=61+7.24375

=$68.24

Papessa [141]

Answer:

23 days

Step-by-step explanation:

Given that the mass of a particular substance is known to grow exponentially at a rate of 1.5% per day

Initial mass = 230 gm

After t days, mass = 325 gm

The equation is

P(t) = 325 = 230 (1+\frac{1.5}{100} )^t\\\frac{325}{230} =1.015^t\\log 1.413 = t log 1.015\\t = \frac{log 1.413}{log 1.015} =\frac{0.1502}{0.0065} \\=23.229

Approximately after 23 days the mass will become 325 gms.
