Aquantity, t, varies inversely with a quantity, r. if t=6, then r=5 what is the constant of variation

constant of variation = 6/5

Step-by-step explanation:

t varies inversely as r

Let k be the constant of variation

t = k/r

t = 6 and r = 5

Substitute the value of t and r

6 = k/5

Make k the subject of the formula

k = 6/5

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
