Umm no se odio las matematicas :(
Answer:
Let C be the cost price of the article. Then:
C(1+30%)=marked price
So:
C(1+30%)=C(1.3)
=1.3C
If the article is then marked down 35%, then its’ price would be:
1.3C(1–35%)=1.3C(.65)
=0.845 or 84.5% of its’ cost
Then:
0.845–1=-0.155
or, a 15.5% loss on the item
Well we do know that 7x9 = 63
I only know 1 way but I dont know if it is Distributive
(3+4) 3 x 3
I think x is 20 I’m not sure tho since it would come out as -10 instead of positive
