If you would like to know how many pounds of each kind of candy must the grocer use to make 100 pounds worth 85 cents a pound, you can calculate this using the following steps:
Candy number 1:
c pounds = ? ... 90 cents a pound
Candy number 2:
d pounds = ? ... 40 cents a pound
c + d = 100 pounds
c = 100 pounds - d
c * 90 cents + d * 40 cents = 100 pounds * 85 cents
(100 - d) * 90 + d * 40 = 100 * 85
100 * 90 - 90 * d + d * 40 = 100 * 85
100 * 90 - 100 * 85 = 90 * d - 40 * d
500 = 50 * d
d = 500 / 50
d = 10 pounds
c = 100 pounds - d = 100 - 10 = 90 pounds
There should be 90 pounds of candy number 1 and 10 pounds of candy number 2.
90 pounds * 90 cents + 10 pounds * 40 cents = 8500 cents per 100 pounds
8500 cents / 100 pounds = 85 cents a pound
The answer is 357 hope it helped
Step-by-step explanation:
The formula is Distance=√(x2-x1)²+(y2 -y1)²
x1 is 5, x2 is 1, y1 is 9, y2 is 6
D = √( 1-5)² +(6-9)²
D = √(-4)²+(-3)²
D = √16+9
D = √25
D = 5 units
