Kurt and maria’s high school is having a newspaper drive. the goal is to collect 3,585 pounds of newspapers. so far, 21% of the goal has been reached.

kurt estimated the number of pounds of newspapers collected by finding 10% of 3,600 and then multiplying the result by 2.

maria estimated the number of pounds of newspapers collected by finding 1/5 of 3,600.

who is right, and why?

a. neither kurt nor maria is right, because 3,500 should be used instead of 3,600.
b. kurt is right, because finding 1/5 of 3,600 is not a good way to approximate 21% of 3,585.
c. maria is right, because finding 10% of 3,600 and multiplying the result by 2 is not a good way to approximate 21% of 3,585.
d. both kurt and maria are right, because 3,585 should be rounded up to 3,600, and 21% of this amount can be approximated by either finding 10% of 3,600 and multiplying the result by 2 or by finding 1/5 of 3,600.
