Answer:
Y=-4x+8
Step-by-step explanation:
A pharmacist has 40% and 80% of iodine solutions on hand. How many liters of each iodine solution will be required to produce 4 liters of a 50% iodine mixture?
.
Let x = liters of 40% iodine
then
4-x = liters of 80% iodine
Using algebra:
.40x + .80(4-x) = .50(4)
.40x + 3.20-.80x = 2
3.20-.40x = 2
x = 4 liters (40% iodine)
80% iodine:
4-x = 4-4 = 0 liters needed (80% iodine)
Answer:
406.67 miles
Step-by-step explanation:
250=28.95(4)+0.33m
250=115.8+.33m
134.2=.33m
134.2/.33=.33/.33m
m=406.666666667
rounded: m=406.67
