If f(x)= -4(9/8)^x, then what is the sum of its y-intercept and its value where X=1?

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

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60
