The revenue made from the order described above was $99.90 and the equation that represents the situation is 4.55(8)+6.35b = 99.90. Find the number of orders that weigh between 0.5 and 1 lbs.

i think it is c, not positive though

step-by-step explanation:

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
