Answer:
[tex]144[/tex] is the increased number.
Step-by-step explanation:
The first step would be to turn the percentage into a decimal. To do that, divide it by 100.
[tex]60 / 100 = .6[/tex]
Then, multiply that by 90.
[tex].6 * 90 = 54[/tex]
Add both together to get the increased price.
[tex]90+ 54 = 144[/tex]
