$29.99 markdown 33 and one third

Mathematics
1 answer:
Sholpan [36]3 years ago
5 0
Original Price: $29.99
Mark down: 33 1/3%
Mark down Price: $20.00

29.99 * 33 1/3 = 29.99 * 0.3333 = 9.99 value of mark down.
29.99 - 9.99 = 20.00 new price.

The problem is not really clear. We can assume that $29.99 is the mark down price. We need to look for the original price.

Mark down price: $29.99
Mark down rate : 33 1/3%
Original Price    : $44.98

29.99 / ((100% - 33 1/3%) / 100%) = 29.99 / ( 66 2/3% / 100%)
29.99 / 0.6667 = 44.98

Jason watched a caterpillar move 16 feet in 8 minutes. Jason says that the caterpillar's unit rate is 0.5 foot per minute. Is Ja
MrRa [10]

Answer:

Jason is incorrect.

The caterpillar's rate is 2 ft/min

Step-by-step explanation:

The rate of motion is defined as the quotient between the distance covered (in our case 16 feet) divided by the time it took to cover that distance (in our case 8 minutes)

Then, the rate is:

rate=\frac{distance}{time} = \frac{16\,\,ft}{8\,\,min} = 2\,\frac{ft}{min}
