2051 kids were surveyed on how they earn money. 47% said parents gave them money, 32% said allowance, 45% said odd jobs, 26% said part-time jobs, and 11% said full-time jobs. Estimate the number of teens who made each of the response and then find the actual number of each and compare.

Answer 1

Estimating?

11 percent is ten percent with ten percent of that added..

205+21=226
26 precent is about 1/4, th
510

32 percent is nearly one third..

700
47 percent is half minus half of ten percent of that.
1025-50=975

Now work out the actual numbers, and compare.

Answer 2

parents = p
allowance = a
odd jobs = j
part time = h
full time jobs = f

all little less than half are p so about 1000, accurately .47*2051 = 964

about 30% are a so about 600
accurately .32*2051 = 656

j little less than for p so maybe 900
accurately .45 * 2051 = 923

h a little more than 1/4 so around 520
accurately .26*2051 = 533

f a bit more than 1/10 so around 210
accurately .11*2051 = 226
