Denise Robb's account statement shows a $210.94 unpaid balance. With a periodic rate of 1.85%, what is the finance charge? She had new purchases of $341.22. What is the new balance?

A) 3.9 dollars

B) 126.38 dollars

Step-by-step explanation:

Given that Denise Robb's account statement shows a $210.94 unpaid balance. With a periodic rate of 1.85%

The finance charge = 1.85/100 × 210.94 = 3.9 dollars

If She had new purchases of $341.22. The new balance will be

341.22 - ( 210.94 + 3.9 )

126.38 dollars

f is the midpoint of

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
