Question

Solve S = P + Prt for t.

Answer 1

i got t=s-p/pr
but it says its incorrect

Answer 2

s=p+prt
minus p both sides
s-p=prt
divide both sides by pr
s-p/pr = t
t=s-p/pr

Answer 3

Answer 4

parentheses are important. when you divide both sides by Pr, you're dividing the whole expression (S-P) / Pr

Answer 5

where do i need to add parentheses ?

Answer 6

Variable case matters, too. Lowercase/capitals need to be the same

Answer 7

S = P + Prt

S - P = Prt
\[\frac{ S-P }{ Pr }=t\]

if it doesn't let you enter fractions, parentheses have to be around S - P

Answer 8

ah it was the variable case that got it wrong

Answer 9

answer was
t=S-P/Pr
didnt even think about that!
