The equation representing pizza purchase and delivery in point slope form is y = 2x + 1 and the delivery fee is $1

The total cost of pizza including delivery can be broken down thus :

  • Cost per pizza
  • Number of pizza purchased
  • Delivery fee (this is a constant)

General form of a point slope equation :

  • y = a + bx
  • y = total cost
  • a = intercept (Constant)
  • b = slope(cost per pizza)
  • x = number of pizzas purchased

From the question :

  • Total cost including delivery = $9 = y
  • Cost per pizza = $4 = b
  • Number of pizzas = 2

Putting the values into the equation :

9 = 4(2) + a

Solve for a

9 = 8 + a

9 - 8 = a

a = 1

This means that delivery fee is $1

The equation in point slope form is thus : y = 2x + 1

She worked a total of 15 hours. If she makes $15 per hour tutoring and $9 per hour at the grocery store and made a total of $159
Ugo [173]

Answer:

11 hours she worked at the grocery store

Step-by-step explanation:

assuming,

the number of hours worked at tutoring = x

the number of hours worked at grocery store = y

which means,

the amount she made at tutoring = x* $15

the amount she made at grocery store = y*$9

we have 2 equations

<em>total number of hours</em>

1) x+y= 15  

<em>total amount she earned</em>

2) x* $15+ y* $9= $159

From equation 1

x+y= 15  

x=15-y

<em>we replace this x value in equation 2</em>

x* $15+ y* $9= $159

(15-y)* $15+ y* $9= $159

(15*15)- 15y+9y=159

225-6y=159

225-159=6y

66=6y

66/6=y

<u>11=y</u>  <em>the number of hours she worked at grocery store. </em>

<em>we place y=11 in our derived x equation</em>

x=15-y

x=15-11

<u><em>x=4 </em></u><em>the number of hours she worked at tutoring. </em>
