Amerchant sold a pen for $6.90 ,thereby making a profit of 15% on her cost calculate the cost of the pen to the merchant to the nearest cent

So you know the merchant made a 15% profit on the pen, so she bought it for a cheaper price. To find the cost of the pen before you have to take the price now, $6.90 and times it by 85%. You do 85% because you subtract the 15% she saved from 100% and you get 85%. So 6.90x.85= 5.865 which rounds to $5.87

The statement is True.

Step-by-step explanation:

" Gravity is the force by which a planet or other body draws objects toward its center. The force of gravity keeps all of the planets in orbit around the sun" .

Anything that has mass also has gravity. Objects with more mass have more gravity.Earth's gravity comes from all its mass.

Gravity is what holds the planets in orbit around the sun and what keeps the moon in orbit around Earth.

Hence, the statement " The Earth and the moon are kept in orbit by gravity and mass"  is TRUE.
