Joy and joanna both purchase party invitations.They both spent the same amount of money. Joy spent $.75 per invitation and $3.25
Ksenya-84 [330]

Answer:

11 invitations each

Step-by-step explanation:

Let the number of invitations they bought be x .

Since they spent the same amount of money, Their total costs would be the same. Hence ;

3.25 + 0.75(x) = 0.5x + 6

0.75x - 0.5x = 6 - 3.25

0.25x = 2.75

x = 2.75/0.25

x= 11 invitations

Kevin bought 3 dvds for 45.99 how much would 7 dvds cost?
Alecsey [184]

Answer:

I am pretty sure the answer would be $107.31. Sorry if I'm wrong.

Step-by-step explanation:

First you take the total of the 3 DVD's (45.99) and you divide that by 3 (number of DVD's) to get 15.33 which is called the unit price. Then, you take your unit price and multiply that by how many items you are going to buy.

45.99 / 3 = 15.33

15.33 x 7 = 107.31
