Need help with parts (b) and (c) of this question
1 Answer
b) We have
\[12012\times \frac{1.5}{100}+5564 \times \frac{3.5}{100}+(x17576)\times \frac{7}{100}= x \times \frac{5}{100}. \]
c) We need to solve the above equation for $x$:
\[180.18+194.74+\frac{7}{100}x1230.32= \frac{5}{100}x \]
\[\Rightarrow (\frac{7}{100}\frac{5}{100} )x=1230.32(180.18+194.74)\]
\[\Rightarrow \frac{2}{100}x=855.40\]
\[\Rightarrow x=\frac{855.40 \times 100}{2}=42,770.\]
