Zach is preparing for an interview and needs to purchase 2 ferns and 7 balloons. Each balloon costs $2.30, and he has $50 total to spend. What is the maximum amount he could spend on each fern?​

$16.95 per fern tree

Step-by-step explanation:

first, you want to find how much money the 7 balloons cost:

7(2.30) = 16.10

second, you want to find how much money you have left AFTER buying 7 balloons:

50 - 16.10 = 33.90

third, divide the money you have left by 2 (2 fern trees) to find the final

33.90/2 = 16.95

i havent done these types of questions in some time, so please let me know if there are any mistakes. good luck! ꒰ ˆ ꒵ ˆ꒱

- "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."
