Question

I buy 4 lb of olives black olives cost $3.00 a pound green olives cost $5.00 a pound I spend 15.50 how many pounds of ea h type of olives

Answer 1

Explanation:

b + g = 4 ...... b = 4 - g

3b + 5g = 15.50

3(4 - g) + 5g = 15.50

12 - 3g + 5g = 15.50

-3g + 5g = 15.50 - 12

2g = 3.50

g = 3.50 / 2

g = 1.75 <==== 1.75 lbs of green olives (or 1 3/4 lbs)

b + g = 4

b + 1.75 = 4

b = 4 - 1.75

b = 2.25 <==== 2.25 lbs of black olives (or 2 1/4 lbs)
