Answer:
The answer is 11 invitations each
Step-by-step explanation:
since they both spent the same amount of money, we will be equating their costs.
We will represent the number of invitations with x
Remember their total costs are equal, therefore, we have:
0.75x + 3.25 = 0.50x + 6.00
Next, we collect like terms thus:
0.75x - 0.50x = 6.00 - 3.25
0.25x = 2.75
Next, we make x the subject of the formula by dividing both sides with 0.25, we therefore have:
0.25x/0.25 = 2.75/0.25
x = 11
Therefore, they each purchased 11 invitations.
