You are making several purchases from the I.B. Electric electronics store. You can buy from this retailer online or in a physica
l store. You have a coupon for 15% off that can only be used in the physical store and a $5.00 off coupon that can only be used online. The sales tax of 6% only applies to the physical store. Shipping for the online store is a flat rate of $8.99. Using this information and the information below, which way would you save the most money?
The answer is -60. this is because the signs implemented in front of numbers give it a sort pattern .
when there are two additions the last number after the positive sign will give a positive number 1 greater than the initial number for example + 5 + 6. Answer afterward will be + 7 and for negative sign eg: - 7 - 8 in the question will give the answer -8 the same number after a negative (-) sign . Hope this helps
