Respuesta :
If 15 postage stamps cost $8.25 then 12 stamps will cost $6.6 if all the stamps cost the same amount.
To calculate the cost of 12 stamps we first calculate the cost of one postage stamp by division.
Since 15 stamps cost $8.25 we can calculate the cost of one stamp by dividing the cost of 15 stamps by 15
cost of one stamp = $8.25 ÷ 15
cost of one stamp = $0.55
Since the cost of one stamp is calculated to be $0.55, we can calculate the cost of 12 stamps by multiplication as follows;
cost of 12 stamps = cost of one stamp × 12
cost of 12 stamps = 0.55 × 12
cost of 12 stamps = $6.6
