First, we’re going to use this formula:
2nd number - 1st number
————————————— x 100%
1st number
If we plug in the numbers to this equation:
23-20
———- x 100%
20
And subtract 23 to 20, the answer to this equation is:
3
—- x 100% = 15%
20
In this case, the percent of increase is 15%.
280*3= 840
3 journals is about 840 grams
It's B because 5 x 4 = 20 and 9 x 5 = 45
When you add them together you get 65
