Answer :
E = 300+30s
300 because of original $300 sum
and 30s because 10% of 300 is 30
and s because each sale is multiplied by 30
so the equation is E = 300+30s
300 because of original $300 sum
and 30s because 10% of 300 is 30
and s because each sale is multiplied by 30
so the equation is E = 300+30s
Answer:
The formula for E is [tex]E=\frac{s}{10}+300[/tex].
The required formula for s is [tex]s=10E-3000[/tex].
Step-by-step explanation:
Consider the provided information.
Janet earns $300 per week plus a commission of 10% on all sales that she makes.
Let Janet sales is represents by s and weekly earning represents by E.
The fixed amount which he earn per week is $300 and Janet earns commission of 10% on all sale.
This can be written as
[tex]E=10\% \times s+300[/tex]
[tex]E=\frac{10}{100}\times s+300[/tex]
[tex]E=\frac{s}{10}+300[/tex]
Hence, the formula for E is [tex]E=\frac{s}{10}+300[/tex]
Now solve the formula for s as shown below:
Subtract 300 from both sides
[tex]E-300=\frac{s}{10}[/tex]
Multiply both sides by 10.
[tex]10(E-300)=10\times \frac{s}{10}[/tex]
[tex]s=10E-3000[/tex]
Hence, the required formula for s is [tex]s=10E-3000[/tex].
