A. Sarah Smartshopper receives ten cents off per gallon on gas for every $100 she
1 answer:
Using proportions, it is found that her discount is of $0.29664.
<h3>What is a proportion?</h3>A proportion is a fraction of a total amount.
In this problem, the total amount she spent on gas is given by:
T = $45.23 + $102.34 + $13.67 + $34.56 + $48.72 + $52.12 = $296.64.
Considering that she receives ten cents off per gallon on gas for every $100 she spends, we apply the <em>proportion </em>to find that her discount is given by:
Her discount is of $0.29664.

= -468
by adding 360 twice we get the coterminal angle 252
252 is in the 3rd quadrant so 180 is the closest angle on the x-axis
ref angle = 252 - 180 = 72
If necessary convert back to radians...
