The equation looks like this:
26=x*3.5+8.50
where x is the number of pen you bought.
We solve it like this:
first, we subtract 8.50 from both sides:
17.50 =3.5*x
now we divide both sides by 3.5:
5=x
so you purchased 5 pens.

Answer:
34.78 is the answer to ur question
Answer:
w=30 l=125
Step-by-step explanation:
Perimeter =2l+2w
p=310
w =width
4w+5 = length(4 times plus 5 the width)
2(4w+5) + 2w = 310
8w+10 = 2w =310
10w=300
w=30
30*4=120 120+5=125 l=125
2(125)+ 2(30)= 250+60 =310
