Answer this question:Rebecca makes her own earrings out of buttons, magnets, and gemstones. For every earring, she uses two magnets, half as many buttons as magnets, and three times as many gemstones as buttons. If Rebecca wants to make 4 sets of earrings, how many gemstones will she need?
Four sets of earrings is 2 * 4 = 8 earrings. Since for one earring, she uses two magnets, for eight earrings she uses 2 * 8 = 16 magnets. Since she uses half as many buttons as magnets, then for 8 earrings she would use 16 / 2 = 8 buttons. Since she uses three times as many gemstones as buttons, then in 8 earrings, she will use 8 * 3 = 24 gemstones.
The answer is 24.

Answer this question:Colin can skip at six times the speed that Brandon can. Brandon can skip at one-third the speed that Tony can. And Tony can skip at twice the speed that Bruce can. At what speed, in miles per hour, can Colin skip if Bruce skips at 1 mile per hour?
Tony can skip at twice the speed that Bruce can, for a speed of 1 * 2 = 2 miles per hour. Brandon can skip at one - third the speed that Tony can, for a speed of 2 * (1 / 3) = 2 / 3 miles per hour. Colin can skip at six times the speed that Brandon can, for a speed of (2 / 3 * 6 = 4 miles per hour).
The answer is 4.

Answer this question:Mark collects money for the homeless. He visits 20 households a day for 5 days and half of those households give him a pair of 20s. How much did he collect?
He got money from 20 / 2 = 10 households per day. So that means he got money from 10 * 5 = 50 households. Each of those houses gave 20 * 2 = $40. So he raised 40 * 50 = $2000.
The answer is 2000.
