It is greater than 37,493.
STatiana [176]
37493 < x < 37503

it is even....so choices so far are : 37494, 37496, 37498, 37,500, 37,502

rounded to the nearest ten is less then the number....

37494 rounded to the nearest ten = 37490.....it is less then the mystery number
and 37502 rounded to the nearest tens = 37500...it is less then the mystery number

ur other choices, when rounded to the nearest ten are greater then or equal to the mystery number...so they dont work

so now we have 2 choices....37494 and 37502

rounded to the nearest thousand is greater then the mystery number....

37494 rounded to the nearest thousand = 37000...that less then...so this wont work

37502 rounded to the nearest thousand = 38000....thats greater then the mystery number....BINGO....ur answer is : 37502 <==

Kendra has $ 4.85 in nickels and quarters. If she has 5 more quarters than nickels, how many of each coin does she have?
yarga [219]

If she were to add 5 nickels ($0.25), then she would have an equal number of nickels and quarters, and her total would be $5.10. An equal number of nickels and quarters gives a multiple of $0.30. $5.10 is 17 times $0.30. The number of quarters Kendra has must be 17, but she has 5 fewer nickels, so

Kendra has 17 quarters and 12 nickels.
