Vivian is at a fair in Coachella Valley, California. Much of the valley lies below sea level. Vivian has brought along an altimeter to measure her elevation at different places in the valley. Vivian’s first ride was on the Ferris wheel. When she sat on the wheel at its lowest point, her altimeter read -9.6 feet. When she reached the top of the wheel, her altimeter read 12.3 feet.

Is the change in Vivian's elevation from the bottom of the Ferris wheel to the top a positive number or a negative number? Why?

Answer: Its a positive number

Step-by-step explanation:

If you look it says she is at sea level which is 0 and she is going up 12.3 feet so its positive.

Since the Hargrove’s younger daughter hadn’t taken part in the mathematical deliberations about the candy to purchase, she was selected to go to the store to buy the family’s Halloween candy. Being less mathematically compulsive than the rest of the family, she really couldn’t care less about how many grams of chocolate and nuts are in the candy. She figured she needed to buy at least 90 pieces of candy so she wouldn’t have to share with her brother and sister like last year. She also knew that her father wasn’t going to give her more than $24. When she got to the store, she saw that Twix-or-Tweats came in bags of 20 bars that cost $6 each. Batterfingers came in bags of 15 bars that cost $3 each.
