A) First, we need to calculate the cost per kg of tomatoes:
Cost of 10kg box = $23.50
Cost per kg = $23.50 / 10kg = $2.35/kg
Now, we can use the unitary method to calculate the cost of a 3kg box:
Cost of 1kg = $2.35
Cost of 3kg = $2.35 * 3 = $7.05
Therefore, the cost of a 3kg box of tomatoes is $7.05.
B) To find the unit price (price per 100g) of the cheese:
Cost of 250g block = $7.85
First, we need to find the cost per 1g:
Cost per 1g = $7.85 / 250g = $0.0314
Now, we can calculate the cost per 100g:
Cost per 100g = $0.0314 * 100 = $3.14
Therefore, the unit price of the cheese is $3.14 per 100g.
A) A 10kg box of tomatoes cost $23.50. Use the unitary method to calculate the cost of a 3kg box.
B)If a 250g block of cheese costs $7.85, find the unit price (the price per 100g)
