Answer:
Part One: $187
Part Two: 11a + 5.5k
Step-by-step explanation:
Part One:
a = 9 (how many adult tickets)
k = 16 (how many kid tickets)
($11 × a) + ($5.50 × k) = total cost
($11 × 9) + ($5.50 × 16)
($99) + ($88) = $187 = total cost
Part Two:
11a + 5.5k
11 is how much the adult ticket costs, you multiply a or the amount of adult tickets in order to get the total cost for adults.
5.5 is how much the kid ticket costs, you multiply k or the amount of kid tickets in order to get the total cost for kids.
you add 11a + 5.5k or the total cost for adults and the total cost for kids to get the total cost.

you will get a total for both as 21
then get the area of the square 36-21=15
so the area becomes 15

The present value that must be invested to get $19,000 after 4 years at an interest rate of 11.5% is $13,013.70
What is simple interest?
The simple interest of an investment is determined as the principal investment, also known as the present value multiplied by the interest rate and the number of years, which means that the future value can be modeled as shown below:
A=PRT+P
A=P(RT+1)
A=future value=$19,000
P=present value=unknown
R=rate of return=11.5%
T=number of years that investment lasted=4
$19,000=P*(11.5%*4+1)
$19,000=P(0.46+1)
$19,000=P*1.46
P=$19000/1.46
P=$13,013.70
