Movie tickets cost $9.95 for adults and $6.75 for students. The writer family buys two adult tickets, three student tickets, and the popcorn and drinks for $26. What is the total amount that they spend

The Writer Family spends $66.15

Step-by-step explanation:

1. Cost of adult tickets: $9.95 + $9.95 = $19.90

2. Cost of student tickets: $6.75 + $6.75 + $6.75 = $20.25

3. Cost of popcorn and drinks: (given) $26.00

4. Add up all costs: $19.90 + $20.25 + $26.00 = $66.15

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

, and

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
