Answer:
Each balloon costs $1
Each banner costs $2
Step-by-step explanation:
First of all, let's write down the equation from this problem.
Let "y" be the cost of the ballon, and let "x" be the cost of a banner. Then the following is true from the question...
4y + 2x = 8
6y + x = 8
Now since both of them are equal to 8 both of them are equal to each other, and so we can get the following equation...
4y + 2x = 6y + x
2x - x = 6y - 4y
x = 2y
Now if we substitute 2y instead of x in one of the previous equations we will obtain...
6y + x = 8
6y + 2y = 8
8y = 8
y = 1
From the equation x = 2y we know that...
x = 2y
x = 2(1)
x = 2
The cost of 0.5 kg of bananas is 393.60 Colones as per the given conversion rates
Conversion rate of 1 USD to Costa Rican Colones = 518 Colones
The conversion rate of kg to pounds given in the question: 1 kg = 2.2025 lbs
Cost of one pound of bananas = $0.69
Bananas required to be purchased = 0.5kg
Converting 0.5kg bananas to pounds = 0.5*2.2025 = 1.10125 pounds
Cost of 1.10125 pound of bananas in dollars = 1.10125*0.69 = 0.7598
Cost of 1.1025 pounds of bananas in Colones = 0.7598*518 = 393.60 Colones
Hence, the cost is 393.60
Therefore, the cost of 0.5 kg bananas in Colones is 393.60 Colones
