Answer:
12 in diameter bed will give better value
Step-by-step explanation:
Given:
Cost of cover 12 in diameter bed = $150
Cost of cover 18 in diameter bed = $300
Find:
Better value
Computation:
Area of bed = πr²
Area of 12 diameter of bed = (22/7)(6)²
Area of 12 diameter of bed = 113.14 in²
Area of 18 diameter of bed = (22/7)(9)²
Area of 18 diameter of bed = 113.14 in²
Area of 18 diameter of bed = 254.57 in²
Compare cost of bed 1 = 113.14 / 150 = 0.75 in per dollar
Compare cost of bed 2 = 254.57 / 300 = 0.84 in per dollar
So,
12 in diameter bed will give better value
X=8y/5
Dhdhdhd did Dodd just
X/18 = 12.6
Multiply both sides by 18.
x/18 * 18 = 12.6 * 18
x = 12.6 * 18
x = 226.8
The number is 226.8.
