WILL GIVE BRAINLIEST Mr. and Mrs. Bailey hope to send their son to college in eleven years. How much money should they invest no

Ronch [10]

Mr. and Mrs. Bailey need to invest $2906.50 so as to send their son to college.

<h3>Compound interest</h3>

Compound interest is given by:

$A=P(1+\frac{r}{n})^{nt}$

where A is the amount after t years, P is initial amount, r is the rate and n is the times compounded per period

Given that n = 1, r = 9% = 0.09, A = $7500 t = 11. Hence:

$7500=P(1+\frac{0.09}{1} )^{1*11}\\\\P=\$2906.50$

Mr. and Mrs. Bailey need to invest $2906.50 so as to send their son to college.

ExtremeBDS [4]

Step-by-step explanation:

The Fall Festival charges $0.75 per ticket for the rides. Kendall bought 18 tickets for rides and spent a total of $33.50 at the festival

0.75 per ticket. So cost of 18 tickets= 0.75 * 18 = $13.5

Kendall spent $13.50 for tickets . Total spent = $33.50

Total spent = ticket cost + admission cost

33.50 = 13.50 + admission

Admission cost = 33.50 - 13.50 = $20

(a) y to represent the total cost , x to represent the number of ride tickets.

'b' represents the admission cost

(b) General form of linear equation is y=mx+b

m = 0.75 and b = admission cost = 20

So equation becomes y = 0.75x + 20

(c) Initially, she has to pay the admission price $20. then 0.75 per ticket.

The value of x changes depends on the number of tickets she wants to buy.

y is the total cost she has to pay for x tickets with admission price

You buy 12 tickets and the total is $120. a student ticket is $9 and an adult ticket is $12. how many student tickets did you bu

N76 [4]

4 adult tickets were sold and 8 student tickets were sold.
How did I get this?

First, let's see what information is given:
12 tickets sold
(S)tudent ticket = $9
(A)dult ticket = $12
Total cost = $120

So, we know student tickets plus adult tickets total up to $12. We can create an equation out of this: S + A = 12

And we know $9S + $12A = $120

The variables represent the amount of tickets sold, which is unknown.
A = 12 - S , substitute this into the second equation.

9s + 12(12-s) = 120
Distribute the 12 into the parenthesis.

9s + 144 - 12s = 120
Combine like terms

-3s + 144 = 120
Subtract both sides by 144, left side cancels out.

-3s = -24
s = -24/-3
s = 8

So, 8 student tickets were sold. Plug the value of s into our first equation.

A = 12 - 8
A = 4 (adult tickets)
