Answer:
$176.3193692 or $176.32 (rounded to two decimal places)
Step-by-step explanation:
It is a compound interest, which means the interest accumulates on an initial amount each period.
The formula is A=P(1+R)^n
A= the total amount P=initial amount R=rate n=time (years)
P=$120 Rate= 8% or 0.08 (decimal) n=5 (years)
A=120 (1+0.08)^2
A=120 (1.469328077)
A= 176.3193692
We know the yint, so lets find the slope. (0,-12) and (8,-2) -2--12/8-0 or 10/8 or 1.25
So, the slope is 1.25
The answer is y=1.25x-12

Step-by-step explanation:The cost of an adult ticket to the show is $5.5
The cost of a student ticket to the show is $4.25
A family is purchasing 2 adult tickets and 3 student tickets. This means that the total cost of 2 adult tickets would be
2 × 5.5 = $11
It also means that the total cost of 3 student tickets would be
3 × 4.25 = $12.75
The total cost of 2 adult tickets and 3 student tickets would be
11 + 12.75 = $23.75
If the family pays $25, the exact amount of change they should receive is
25 - 23.75 = $1.25
