The price of candy bars can be determined by the equation p= 1.25n, where p is the price and n is the number of candy bars. What is the constant of proportionality (unit rate)

1.25 is the constant of proportionality

Step-by-step explanation:

Given:

p = 1.25n

Where,

P = price of candy bars

n = number of candy bars.

What is the constant of proportionality (unit rate)?

The constant of proportionality is 1.25

For example, if number of candy bars is 10, find the price

n = 10

p = 1.25n

= 1.25 * 10

= 12.5

P = 12.5

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
