The sale is 33% off notebooks. This can be found by first subtracting .8 from 1.2

1.2-.8=.4    Now divide .4 by 1.2 to get your answer.

\frac{.4}{1.2}=.33

.33=33%

You can also solve this mentally because if you know your basic multiplication tables, 3*4=12 and so \frac{2}{3} of 12 would equal 8.

In the question it is already given that the actual cost of each notebook is $1.20. For the weekend, the notebooks would sold at a discounted rate of $0.80
he
The amount of discount during the weekend = (1.20 - 0.80) dollars
                                                                       = 0.40 dollars
So the amount of discount given during the weekend is $0.40
Now we need to find the percentage of discount given during the weekend.
Then
Percentage of discount during the weekend = (0.40/1.20) * 100
                                                                       = 0.33 * 100
                                                                       = 33
Then the percentage of discount given is 33%.

Write and solve a system of equations to determine how many tickets were sold before and at the music festival. PLEASE HELPPP
strojnjashka [21]

b = number of tickets sold before

a = number of tickets sold after

cost of a ticket = number of tickets times cost per ticket

before cost = 39.95b

after cost = 54.95a

total cost = 925000

39.95b + 54.95a = 925000

total number tickets = 20000

b + a = 20000

we have

39.95b + 54.95a = 925000

b + a = 20000

multiply second equation by -39.95 and add to first equation

39.95b + 54.95a = 925000

-39.95b-39.95a = -799000 +

0b+15a = 126000

15a = 126000

divide bot sides by 15

a = 8400

sub back

b + a = 20000

b+8400 = 20000

minus 8400 both sides

b = 11600

11,600 tickets sold before

8400 tickets sold after
