=  \frac{ - 1}{ \:  \: 2} x + 2 = x + 7

=  \frac{ - 1}{ \:  \:  \: 2} x + 2 - x = 7

=  \frac{ - 3}{ \:  \:  \: 2}x  + 2 = 7

=  \frac{ - 3}{ \:  \ \:  2}x = 7 - 2

=  \frac{ - 3}{ \:  \: \:  2} x = 5

x = 5 \:  \div  \frac{ - 3}{ \:  \: \:  2}

x = 5 \times  \frac{ \:  \:  \: 2}{ - 3}

x =  \frac{ - 10}{ \:  \:  \: 3}

∴  \frac{ - 1}{ \:  \:  \: 2}  \times  \frac{ - 10}{ \:  \:  \: 3}  =  \frac{ - 10}{ \:  \:  \: 3}  + 7

chris can be paid in one of two ways. plan a is a salary of $370 per month, plus a commission of 8% of sales. plan b is a salary
JulijaS [17]

Answer:

For a sale value greater than $7200 the plan a is profitable.

Step-by-step explanation:

Let us assume for a sale of $x, Chris will choose plan a.

Now, in plan a, a commission of 8% of sales and $370 per month, is the salary.

So, for a sale of $x the salary is $(370 + 0.08x) per month.

And, in plan b, a commission of 3% of sales and $730 per month, is the salary.

So, for a sale of $x the salary is $(730 + 0.03x) per month.

Now, for selecting plan a, the condition is  

(370 + 0.08x) > (730 + 0.03x)

⇒ 0.05x > 360

⇒ x > 7200

Therefore, for a sale value greater than $7200 the plan a is profitable. (Answer)
