Step-by-step explanation:
Let F = The number of $5 bills and T = the number of $10 bills. She has 15 bills total, so:
F+T = 15
T = 15-F
She has $120 total:
$120 = ($5)*F + ($10)*T
$120 = $5*F + ($10)*(15-F) [Substitute 15-F in place of T]
120 = 5F + 150 - 10F
-30 = -5F
6 = F
Check:
T= 15-F = 15=6 = 9
$120 = ($5)*6 + ($10)*9
$120 = $30 + $90
$120 = $120
Percentage wise, we are understanding that 100% of the population equals all 3,600 students, and that only 40% eat cold pizza for breakfast. This means that 60% do not eat cold pizza for breakfast, so:
3600 students x 0.6 (or 60/100) = 2,160 students who do not eat cold pizza for breakfast.
Rounding as accorded to the question, the answer would then be 2,200 students when rounded to the hundredths place.
3 is the correct answer, you could always check your work by dividing 0.000027 by 3 which would get you 0.000009. I hope this helped =)
