Drew soda lemonade and apples at the school Fair he's sold a total of $64 if he sold $21 in lemonade how many dollars worth of apples did he sell

$43

Step-by-step explanation:

We know the total amount of money Drew earned from selling = $64. Since he is only selling two items, lemonade and apples, we can turn the info into an equation: lemonade + apples = $64 (or L + A = 64)

We also know that he sold $21 in lemonade. If we plug that into our new equation, it looks like this:

21 + A = 64

From there we just need to find A (the amount of money he earned from selling apples). We can do this by subtracting 21 from 64:

A = 64 - 21

A = $43

- "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."
