<h3>Part C</h3>
Explanation of steps
- 1 - note the point 16 on the number line
- 2 - move left by 9 points on the number line
- 3 - note point 7 as answer
LCM of 14 and 22 is 154, and the GCF is 2
First let us calculate the total cost before tax:
1.06 * cost = 16.43
cost = 15.5
Therefore the cost of sunscreen is:
2 * Sunscreen + 6.50 = 15.5
2 * Sunscreen = 9
Sunscreen = $4.50
<span>Hence each bottle of sunscreen cost $4.50</span>
