What is the mean round to the nearest tenth if needed value 1 2 3 4 5 frequency 7 1 3 2 2 ?

1 * 7 + 2 * 1 + 3 * 3 + 4 * 2 + 5 * 2 =

7 + 2 + 9 + 8 + 10 =

36

Now we need to divide 36 by the total frequency: 7+1+3+2+2=15

36 / 15 = 2.4

let x be the money she spent so that she can earn the free t-shirt.
