Step-by-step explanation:
Your Aunt Lina wants to be fair and wants you to buy an equal amount of hamburgers as turkey burgers for everyone at the family reunion. How many of each burger did you buy?
Since we are buying an equal amount of both burgers then:
Let us represent the amount of each as x
You spend $105 on hamburgers and turkey burgers. You pay $1.50 for each hamburger and $2 for each turkey burger.
Hence:
$1.50x + $2x = $105
$3.50x = $105
x = $105/$3.50
x = 30
Therefore, the amount of each burger than you bought = 30
