if 100 envelopes cost 70 cents, how much would 250 cost

Question:- if 100 envelopes cost 70 cents, how much would 250 cost

Answer

In the question, it is said that 100 envelopes cost 70 cents. This implies that for the 1 envelope, cost equals to 0.7 cents (division of 70 cents by a number equaling hundred envelopes). Assuming that we are interested in the cost of 250 envelopes, we should divide the price of one envelope (0.7 cents) to know how much each single unit costs and multiply this figure by accordingly. Calculating this, 0.7 cents x 250 envelopes gives an answer of 175cents. So, if a package of 100 envelopes costs seventy cents then the price for two and half hundred would be one dollar seventy five. The main stages include finding the per unit cost through division of total cost by quantity and then multiplying this amount to new desired quantity for obtaining updated total value. For illustration of the process and calculation leading to this final total cost, this work is displayed in a sequential, logical order.
