1.08421X10^25 As for solving it... use a calculator lol that's all we do especially out of school. If you want to know how to do it without one head to Khan academy.
Answer:
3.45
Step-by-step explanation:
if 4 pints are 13.80 you would have to divided 13.80 by 4 and 4 by 4 to get 1 over blank. The denominator would be 3.45 which would be the amount 1 pint cost. If you don't want to do it as fractions you can simply divide 13.80 by 4.
3p-(-20)=50
3p+20=50 subtract 20 from both sides
3p=30 divide both sides by 3
p=10
