Answers:

Answer 1

Answer:

1750

Step-by-step explanation:

Earns per week: $560

Total sales per week: $x$

Weekly commission on sales: 0.08$x$

Total Earning per week: $560 + 0.08x$

$560 + 0.08x \geqslant 700$

Simplifying this inequality:

$560 + 0.08x \geqslant 700\\0.08x \geqslant 700 - 560\\0.08x \geqslant 140\\\\x \geqslant \frac{140}{0.08}\\\\x \geqslant 1750$

Her sales must be at least $1750.
