Abakery charges $14.00 for 4 croissant sandwiches. what is the unit rate?

The unit rate is given as $3.5 per croissant sandwiches.

Step-by-step explanation:

The total charges are $14.00

There are 4 such croissant sandwiches.

The unit rate is given as, A rate is a special ratio in which the two terms are in different units. When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates.

Thus the unit rate is given as ,

=

Thus the unit rate is given as $3.5 per croissant sandwiches.

- "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."
