A: 6 brushes and 5 palettes cost $17.
B: 3 brushes and 2 palettes cost $8.

What if we make the number of brushes the same in both cases?

If we realise, 2 complete sets of B will also get us 6 brushes.

A: 6 brushes and 5 palettes cost $17.
B: 6 brushes and 4 palettes cost $16.

The difference between the two cases is only the one extra palette which costs $1.

Algebra can be used, but certainly not at the P6 level. You will need a Secondary 2 level of algebra to solve this question using algebra.
