If I go out to eat and my food is $20.98 and the tax is 8.6% how much would I have to pay all together?

$22.78

Step-by-step explanation:

Cost Price: 20.98

Tax is 8.6% of this: 20.98 x 0.086 = 1.80

Total price = Cost Price + Tax:

Total = 20.98 + 1.80 = $22.78

Brainliest would be nice :)

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

, and for

(0.2)+(-8)=0.3+-3+0.3m is the equation i guess? ?
