23 gram remains

Step-by-step explanation:

62÷12.4=5 half lives

after 5 half lives it has been reduced by 1/2×1/2×1/2×1/2×1/2=1/32

after 62 hours, 1/32×750=23 grams

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value
