A tape manufacturer reduces the price of its heavy duty tape from $30 to $28 a reel, and the price of regular tape from $20 to $19 a reel. a computing center normally spends $1600 per month for tapes and 3/5 of this for heavy duty tapes. how much will they save per month under the new prices?

3/5 of 1600 = $960 spent for heavy duty tapes

1600 - 960 = $640 spent for regular tapes

The company normally bought

960 : 30 = 32 heavy duty tapes

640 : 20 = 32 regular tapes

With the new prices, the company is paying

32 * 28 = 896 for the heavy duty tapes

32 * 19 = 608 for the regular tapes

The company is saving

960 - 896 = $64 for the heavy duty tapes

640 - 608 = $32 for the regular tapes
