Answer:
Morgan has to work 1300 hours.
Step-by-step explanation:
Let x represent number of hours.
We have been given that Morgan earns $26 per hour plus 3.5% of her sales.
The amount earned from working x hours without sales would be
.
Since she need to make $33,800 per year without sales, we will equate money earned in x hours by $33,800 to find number of hours as:

Answer:
A = 45 units^2
Step-by-step explanation:
This is a trapezoid
A = 1/2 (b1+b2) h
b1 is the top = 7
b2 is the bottom = 11
h = 5
A = 1/2 ( 7+11) *5
A = 1/2 ( 18)*5
A = 45 units^2
