Answer:
a) 675 000
b) 685 000
Step-by-step explanation:
The population of a town is 680 000 correct to the nearest 10 000.
a) To find it lower bound, we level of accuracy by 2 and then subtract from 680 000
The lower bound is:
680 000-5000=675,000
Therefore the least possible population of the town is 675 000
b) We repeat the same process to find the upper bound
680 000+5000=685,000
Answer: $37
Step-by-step explanation:
The remaining balance, B (in dollars), on the card after buying x prints is given as $50.00 - 0.15x.
Therefore, the remaining balance on the card if Jane bought 20 prints will be:
= $50.00 - 0.15x.
= $50.00 - 0.15(20)
= $50.00 - $3.00
= $47.00
