Kate, un deliver canned goods to the local shelter. last week, she delivered 5 boxes with 100 can each,2 crates with 1,000 cans, and 4 bags with 10 cans each. how many cans did she delivered last week?

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
