The 3rd questions answer is: In order to solve this, you need to add 20% of the $7.50 TO the $7.50.
First, multiply 0.20 x $7.50 = $1.50
Then, add the $1.50 to the original $7.50 because the price is increasing by 20%, so the new price of the ticket is $9.00. (I got this answer because someone else asked this question on BRAINLY and this was an answer, it’s correct btw)
