The age of jane is 80% of the age of alice. if we add both ages the result is 45. find the age of jane and alice

Age of Alice = 25, Age of Jane = 20.

Step-by-step explanation:

Let age of Alice = x

Then age of Jane is 80% of the age of Alice

=> Age of Jane = 80% of x = 80/100 * x = 0.8x

Adding the two ages gives 45.

The two ages are x and 0.8x.

The sum of the two ages is x+ 0.8 x = (1+0.8)x = 1.8x.

=> 1.8 x = 45

Dividing both sides by 1.8, x = 45/1.8

=> x= 25

But x represents the age of Alice.

So age of Alice is 25.

Age of Jane = 0.8* 25 = 20

Verification: Adding the two ages gives 45.

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
