Agroup of students held a fundraiser last year and raised $950 for charity. this year, they raised $1,045. what is the percent change in the amount the group raised?

Hello there!

The students wanted to raise $950, which will be called the %100.

They raised $1,045, the quotient betwen this and the initual amount they wanted is:

$1,045/$950 = 1.1

this means that $1,045 = 1.1*$950 = $950 + 0.1*$950

Then, if $950 is the 100%, $1,045 is the 1.1*100% = 110%

the difference is 110% - 100% = 10%

This means that the percent change in the amount the group raised is 10%.

the expected value of the random variable : 0, 1 and 2
