Question

1. Adam burns 850 calories when he runs for one hour, suppose he runs 3 hours .

Answer 1

Answer:

1. If Adam burns 850 calories per hour

850×3=2550 calories for 3 hours

2. If the original price is 200$ and the discount is 30%

We get:

200 × 30

Which can be written as

200×0.3

=60

So 30% of 200 is 60

now to calculate the new price

200-60=140$

The new price is 140$
