Because it is greater, larger numbers are on the right of the number line...
A- 98+89+123=310 (boys)
A-102+105+117=324 (girls)
B-324-310=14 I found my answer by subtracting the girls from the boys and I got 14
C-They will need to hire 24 more teachers because if you add the students together you will get 644 then you divide it by 20 and you get 32 but since they already have 8 teachers you would just subtract 8 from 32 wich you get 24

The given function is

To find the inverse, we interchange x and y to get:

We now solve for y by taking antilogarithm.

Therefore the inverse of the given exponential equation is the logarithm function
