Reduced by 60%=4/5 Original price * 0.4=£7.98 Original price=7.98/0.4=19.95 ∴ Original price= £19.95 

Sub in her values to see if the LHS and the RHS of the equation equate:

w=1:  3(1)-(1)^3=2  >>>  3-1=2  >>>  2=2  ✅

Therefore 1 is a correct value.

w=-1: 3(-1)-(-1)^...

Expressed as fractions of the whole group, boys are 9/16 of the group and girls are 7/16 of the group.

We can use algebra to work out the total group number. For our working, ...

This question is looking at integration by parts. Therefore, we need to split the integral into two parts.

Part A will be x³ and Part B will be e^x .
