Answer:
$49.82
Step-by-step explanation:
To find the cost of the watch with tax, multiply the price by 1.095:
45.5(1.095)
= 49.8225
Round to the nearest hundredth:
= 49.82
So, the final cost is approximately $49.82
Answer & Explanation:
For this question, you need to figure out the length and the width because the area is directly related to them (A = l*w).
What we do know is that the perimeter is 36 inches. Since the perimeter is equal to P = 2l + 2w, we can say:
P = 36 = 2(3 + 2w) + 2(w), where the length l is 3 + 2w
Solve for w first, then solve for l. Use these values to find the area.
