Answer:
factorisation
Step-by-step explanation:
I don't know what your asking
I hope this helps you
x^2/3 [x^2/3.x^-1/4)^6.1/3.2
x^2/3[x^8-3/12]^4
x^2/3 [x^5/12]^4
x^2/3.x^5/12.4
x^2/3.x^5/3
x^2+5/3
x^7/3
You would do for pens
22 x 1.15 =25.30
And for markets
15 x 2.05 = 30.75
And since you are trying to find how much he spent in all you would add the two sums
25.30 + 30.75 = 56.05
The answer for this problem is y=2X
