Answers to HW: SPIDER TOWING A FRIED EGG Today in class students worked out another tax percent problem, then split up into two groups to begin to explore simple interest.
Today in class students began in smart block with a menu from a restaurant to look at and price out a very expensive (as it turned out) meal. During class we picked up where our discussion of tax and tip left off for our meal and we completed our calculations. Students then took the calculating percent quiz. Those who finished early had the opportunity to try a different weekly HW sheet and give me feedback.
Today in class students reviewed finding percents by several different methods, and then we began to discuss calculating tax, tip, and commission.
Today in class students took a really fast look at the power point about finding the percent of change from the google classroom. You may find it there to complete your notes. We moved on to learn about using mental math (mostly) to find the percent markup and markdown. There is another way to do these in a video lesson on the google classroom.
Answers to HW: 1. whatever you think it will cost... 2. $20 3. $15 4. $12 5. how did you do with your guess... 6. ESTIMATE: an item from the long table is first 50% off, so it drops in price from $50 to $25. Then another 25% is 1/4 of $25, so about $6 more discount - down to $19. Then another 20% off is 1/5 of $19, so about $4 more off - down to $15. 1% of $15 is $0.15, and 6 of those is $0.90 so that's tax added. My total is about $16. 7. 1/2 of $80 is $40, then 1/4 of $40 is $10 so the cost is down to $30. !/5 of $30 is $6, so now the cost is down to $24. $24(7.5%) = $1.80, plus $24 = $25.80 total cost for the $80 item. 8. You have $100 to spend. You cannot afford the $500 item even with all of the discounts. Do the math of the discounts to prove it. In addition, and $80 item you just bought from that table cost $25.80 and when you divide 500 by 80 and get 6.25...well $25.80 x 6 is more than $100. Today in class students worked to learn how to solve percents by using proportions and cross products. We reviewed converting decimals to percents to fractions.
Today in class students completed the 2nd quarter benchmark.
