6sweets cost 42p altogether how much do 8 sweets cost?

The best thing to do is to find the cost of one sweet, and to do this, divide 42 by 7.
42/7= 6
Therefore, one sweet costs 6p.
To find the cost of 8 sweets, you've got to multiply 6 by 8, and this gives you 54p.
Therefore, 8 sweets cost 54p
Hope this helps :)

Q-P

Step-by-step explanation:Q in standard form is x^5+2x^4-2x^3-x^2-6 and if you subtract P (x^4+3x^3+2x^2-x+2) you get x^5+x^4-5x^3-3x^2+x-8
