24) $230.45

Step-by-step explanation:

25%=25/100=0.25

0.25*357.35=89.38 (rounded to the nearest hundredth)

357.35-89.38=267.97

Now, we have the 25% discount, it is the same thing for the 14% discount.

14%=14/100=0.14

267.97*0.14=37.52(rounded to the nearest hundredth again)

267.97-37.52=230.45

Therefore, total cost is $230.45

15 meter/second=   which is the required answer.
