Let the number of bags to be purchased be x
Option Val : 250 + 1.50x
Option Sally : 100 + 4x
For Val to be the cheaper option:
250 + 1.5x < 100 + 4x
100 + 4x > 250 + 1.5x
100 + 4x - 100 > 250 + 1.5x - 100
4x > 150 + 1.5x
4x - 1.5x > 150 + 1.5x - 1.5x
2.5x > 150
x > 150 ÷ 2.5
x > 60
To make Val the cheaper option, he needs to buy more than 60 bags of lettuces.
330 ft; 150 + 150 = 300; 960 - 300 = 660; 660 ÷ 2 = 330
Answer: 4.02 c
Step-by-step explanation:
so the area of a circle is equal to A=pi multiplied by the radius to the second power. And since that’s half a circle it would make sense for the area to be half of the full circle. The radius (half of the diameter and the area from the center of the circle to the outer edge.) is shown as 1.6ft, 1.6^2 is 2.56 and multiplied by pi that is 8.04 half of that is 4.02.
