Brandon earns a rebate each month on his meals and movie tickets. He earns $0.50 for each movie ticket and $2 for each meal. Las
AURORKA [14]

Let ticket be x and meal be y

So $0.50 for each movie ticket = 0.50x

$2 for each meal = 2y


He purchased 22 tickets, so x = 22

0.50 * 22 = $ 11


Now the total value is $25 (with both ticket and meal)

total = t

0.50x + 2y = t

you know x = 22 and t = 25

11 + 2y = 25


Part A)

2y = 25 -11

y = 14/2

y = 7

Number of meal is 7


Part B)

(don't know about part B)

0.50x + 2y = 25

0.50(22) + 2(7) = 25

11 + 14 = 25

25 = 25

Solve for B - PLEASE HELP IMMA DIE
Marta_Voda [28]
First, you would have to add d to both sides to get rid of it
x+d=ab+c/b
Then you would multiply b by both sides to get rid of the b in the denominator
x+d(b)=ab+c
After that, you would subtract c from both sides
x+d(b)-c=ab
Then you would divide both sides by a
x+d(b)-c=b
------------

Using the formula for interest:

F = P (1 + r/n)^t

Where:
F = future value
P = Principal value
r = interest rate per year
n = interest period
t = duration

Substituting the given values:
F = 200 (1 + 0.32/12)^1
F = 205.33

To obtain the interest, we subtract the principal value from the future value. This is shown below:

Interest = 205.33 - 200 = 5.33

Among the choices, the answer is A.
