I made a typing error on last post so I thought I would try again . thanks for your help.
Use the percent equation to answer the following.

solve the percent equation for b.
percent equation is a= p% . b

i saw in text it set up as cross products a/b = p/100.

I thought about putting formula b=p/a for answer or b = 100 using 1 for a, p

  • algebra - ,

    a = P% b.
    Change % to decimal:
    a = (P%/100%) * b,
    a = (P/100)b,
    Multiply both sides by 100/P:
    b = 100a/P.
