Janet earns $300 per week plus a commission of 10% on all sales that she makes. Write a formula for E, Janet’s weekly earnings, in terms of s, her sales for the week. Then solve your formula for s.  _____________________________________________________________________

Sagot :

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].
