a)

C=$343.00,M=S×30%100%=0.3SC=\$343.00, M=S\times\dfrac{30\%}{100\%}=0.3S

S=C+MS=C+M

Substitute


S=343+0.3SS=343+0.3S0.7S=3430.7S=343S=$490S=\$490



b)



M=0.3S=0.3($490)=$147M=0.3S=0.3(\$490)=\$147MC100%=147343100%=42.857%\dfrac{M}{C}\cdot100\%=\dfrac{147}{343}\cdot100\%=42.857\%

The rate of markup based on cost is 42.857%.42.857\%.
