The question is an illustration of slopes or rate of change.

The price of each item at the bake sale is $1.50

Let:

  • <em>x represents the number of items</em>
  • <em>y represents the amount in the cash box</em>

<em />

So, we have:

(x_1,y_1) = (10,60.00)

(x_2,y_2) = (25,82.50)

The slope represents the price of each item, and it is calculated using:

m = \frac{y_2 - y_1}{x_2 -x_1}

So, we have:

m = \frac{82.50 - 60.00}{25 - 10}

m = \frac{22.50}{15}

m = 1.50

Hence, the price of each item at the bake sale is $1.50

The base of a triangle is 4 cm greater than the
Anna35 [415]

Answer:

Step-by-step explanation:

Formula for area of a triangle:

Height x Base /2

Base (b) = h +4

Height = h

h + 4 x h /2 = 30cm

=> h +4 x h = 60

=> h+4h =60

=> 5h = 60

=> h = 12

Height = 12

Base = 12 +4 = 16

Sergio [31]

Answer:

  • y = 7.5x + 20

Step-by-step explanation:

As per the graph, the y-intercept is 20 which is the initial amount.

Another marked point has coordinates (4, 50).

<u>The slope is:</u>

  • m = (50 - 20)/4 = 7.5

<u>The equation of the line is:</u>

  • y = 7.5x + 20

$20 is the initial deposit and weekly deposit is $7.5
