C² = a² + b²
c² = 17.5² + 47.1²
c² = 306.25 + 2218.41
c² = 2524.66
 c ≈ 50.2

It is correct.

olga nikolaevna [1]

Answer:

$119

Step-by-step explanation:

Let

x -----> the number of skaters

y -----> the cost for birthday parties

we have the points

(10,107) and (15,137)

step 1

Find the slope of the linear equation

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

substitute the values

m=\frac{137-107}{15-10}

m=\frac{30}{5}=6\ \frac{\$}{skater}

step 2

Find the equation of the line in point slope form

y-y1=m(x-x1)

we have

m=6\\point\ (10,107)

substitute

y-107=6(x-10)

step 3

Convert to slope intercept form

y-107=6x-60

y=6x-60+107

y=6x+47

step 4

How much would a party for 12 skaters cost?

For x=12 skaters

substitute the value of x in the equation and solve for y

y=6(12)+47

y=\$119
