Answer:
The answer would be 40!
Step-by-step explanation:
Estimating ~ rounding
I would round 24% (20%), and 289 (300).
using the formula:
= %/100,
I'm looking for "IS"
I multiply 20 (just 20, no percent) by 200 = 4000.
Then I divide by 100 to get the "IS".
That's how I got my answer!
Hope this helps!
Life expectancy of dollar bill = d
life expectancy of coin = c
d = 1/20 c
substitute value in for c (30)
d = 1/20 * 30
d = 30/20
d = 1.5
life expectancy of a dollar bill = 1.5 years
The answer is 6. you just count the boxes in between the two points
