At the farmers market, Nathaniel buys two dozen oranges at $3.50 per dozen, four kilograms of apples at $3.25 per kilogram, two kilograms of carrots at $1.90 per kilogram, and one kilogram of potatoes for $1.20. He received a 5% discount off his total bill. How much money did Nathaniel spend on fruits and vegetables at the farmers market?

Oranges: 2x3.50=7
Apples: 4x3.25=13
Carrots: 2x1.90=3.80
Potatoes: 1.20
Cost: 7+13+3.8+1.2=25

Discount: 25x0.05=1.25
Total cost: 25-1.25=23.75

He spent $23.75 at the farmers market.

He spent $23.75 at the farmers market.

What is Unitary method?

It is a method where we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.

For example

. There are 5 ice-creams. 5 ice-creams cost $125.

Step 1: Let’s find the cost of 1 ice cream. In order to do that, divide the total cost of ice-creams by the total number of ice-creams.

The cost of 1 ice-cream = Total cost of ice-creams/Total number of ice-creams = 125/5 = 25. Therefore, the cost of 1 ice cream is $25.

Step 2: To find the cost of 3 ice-creams, multiply the cost of 1 ice cream by the number of ice-creams. The cost of 3 ice-creams is cost of 1 ice-cream × number of ice-creams = 25 × 3 = $75. Finally, we have the cost of 3 ice-creams i.e. $75.

Given:

2 dozen oranges = $3.50 per dozen

4 kilograms apples = $3.25 per kilogram,

2kilograms of carrots =$1.90 per kilogram,

one kilogram of potatoes =$1.20.

Now, finding the cost for 1 dozen each

Oranges:

2x3.50=7

Apples:

4x3.25=13

Carrots:

2x1.90=3.80

Potatoes: 1.20

Total Cost:

7+13+3.8+1.2=25

Now discount = 5%

So, Discount: 25x0.05=1.25

Final cost= 25-1.25=23.75

Hence, He spent $23.75 at the farmers market.
