Me figure out the one on the bottom

The business had 11 bicycle rentals and 9 in-line skate rentals today.

Step-by-step explanation:

a) Let b represent the number of bicycle rentals and s represent the number of skate rentals.

... b + s = 20 . . . . . . . . the company had 20 rentals today

... 25b +20s = 455 . . . . rental revenue today was $455

b) Subtract 20 times the first equation from the second.

... (25b +20s) -(20b +20s) = (455) -20(20)

... 5b = 55 . . . . . collect terms

... b = 11 . . . . . . . divide by the coefficient of b

The value of s can be figured from either equation. The first is generally simpler: s = 20 -b = 20 -11 = 9.

There were 11 bicycle rentals and 9 skate rentals.

if you meant, "on the way from (3, 2) to (3, 14):

x does not change; y increases by 12.

ensure that you have copied down this problem correctly.   .

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
