Answer:

Step-by-step explanation:

First, find the slope using the slope formula. The slope is 3.

Now plug in any of the x and y values and the value of the slope into the slope-intercept form equation to solve for b.

9=3(3)+b, solve for b

b=0, Now convert the equation y=3x into slope-intercept form.

y-9=3(x-3) This is the equation of the line, the plant will be about 36 cm tall after 12 months.

Answer: Ruth have to make 7 hats to break even.

Step-by-step explanation:

Break even point is a point where Cost = Revenue.

Let x be the number of hats sold.

Given: Cost of booth = $63

Each hat cost = $10

Selling price for each cost = $19

As per given,

Total cost = Cost of booth+ (Cost of each hat)(Number of hats)

= 63+10x

Total selling price = 19x

For break even,

63+10x=19x

9x=63

x=7

Hence, Ruth have to make 7 hats to break even.
