hi ! so the answers are below ...
<h3>1. we need to add both angles to find angle QST</h3><h3> <u>5</u><u>2</u><u> </u><u>+</u><u> </u><u>4</u><u>7</u></h3><h3> <u>=</u><u> </u><u>9</u><u>9</u></h3>
<h3>2. since the angles are on a straight line, to find the angle NPM we need to subtract the given angle with 180⁰ since the total of a straight line is 180⁰ ( hope you understand )</h3>
anyways...
<h3> <u>1</u><u>8</u><u>0</u><u> </u><u>-</u><u> </u><u>7</u><u>9</u></h3><h3> <u>=</u><u> </u><u>1</u><u>0</u><u>1</u></h3>

=> Price of the bike: 540$
Hope this helps!
