Answer:
width=18cm
Step-by-step explanation:
perimeter= 2(l+b)
90=2(27+b)
90/2=27+b
45-27=b
b=18cm
So, 30% is 0.30, but since you are taking off 30%, you are going to have 70% of the price which is 0.70. The word "of" lets you know that you are going to multiply. So, what you do is 150•0.70=105. The discounted price is $105
I just solved it and I'm pretty sure its only one solution, I took the bottom equation multiplied it by -3 then i canceled out the equations and got 9. So that would make it C.
