A chair’s regular price is $349. It is on clearance for 30% off, and a costumer uses a 15% of coupon after that. What is the fin
makkiz [27]

Answer:

The final cost is $207.65

Step-by-step explanation:

Regular price of the chair is $349

with 30% off,

(30/100)*$349 = 0.3*$349

= $104.70

actual cost is $349 - $104.70 = $244.30

For a customer using 15% off coupon

15% of actual cost

(15/100)*244.30 = 0.15*244.3

= $36.65

Final cost is $244.30 - $36.65

= $207. 65

mariarad [96]

Brainliest pls?

Answer:

They could cover 90 kilometres in 6 hours, after the terrain changed.

Step-by-step explanation:

Their speed, when they were traversing through the marsh, is:

speed = distance/time

s = 20 km / 4hr

s = 5 kmph

If their speed tripled, then it will be: 5*3 = 15 kmph

distance = speed * time

d = 15 km/h * 6h

d = 90 km

They could cover 90 kilometres in 6 hours, after the terrain changed.

you want to find the x value so you want to isolate x to do this you have to subtract 2x on both sides. After you have accomplished this you add 20 on both sides once again and then you divide what your answer from what you added by three.
