Pryia and 3 friends go out to dinner and split the cost equally. The meal costs $98, tax is 9% and they leave a 20% tip based the cost of the meal. How much money does Pryia need?

$42.14

Step-by-step explanation:

Given data

Cost of meal= $98

tax= 9%

Tip= 20%

Let us find the amount of the tax and the tip

Tax

=9/100*98

=0.09*98

=$8.82

Tip

=20/100*98

=0.2*98

=$19.6

Hence the total amount paid is

=98+8.82+19.6

=126.42

The amount paid by Pryia

=126.42/3

=$42.14

-10i^2-4i

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
