When do we use the distributive property? MCC6.NS.4 - Find the greatest common factor of two whole numbers less than or equal to 100 and the least common multiple of two whole numbers less than or equal to 12. Use the distributive property to express a sum of two whole numbers 1 – 100 with a common factor as a multiple of a sum of two whole numbers with no common factor

Sales Tax You want to buy the following items at an office supply store: desk, $149.99, chair, $69.99, printer, 129.99, copy paper, $39.99, binder, $2.99, poster, $0.25, index cards, $1.29, four-pack of pilot v5 pens, $5.25, sticky notes, $2.49, white out tape, $1.19, and desk calendar, $7.99. The sales tax is 7%. What is the total cost of all the items including the sales tax? How did you find this cost? Would you find the tax of each item separately, then add all the items together? Is there a faster way?
