Answer:

70kg

Step-by-step explanation:

Firstly, because nothing else changed about the treasure chest apart from the amount of treasure when the mass increased, the difference in mass must be the mass of the 1/4 chest of treasure which was added.

712 - 498 = 214kg

Now that we know that 1/4 chest's worth of treasure has a mass of 214kg, we can multiply this by 2 to find the mass of 1/2 a chest of treasure (without the chest):

214 x 2 = 428 kg

We now know that since 1/2 a chest of treasure has a mass of 428kg, the difference between the mass of the chest AND treasure when it is half full must be the mass of the box:

498 (mass of chest and 1/2 chest worth of treasure) - 428 (mass of just 1/2 chest worth of treasure only) = 70kg (mass of chest only)

We can check this by using the other given mass as well. 214 x 3 = 642kg

This means 3/4 of a chest's worth of treasure only, has a mass of 642kg, meaning the extra mass in the 712kg must be the mass of the chest:

712 - 642 = 70kg

The chest has a mass of 70kg.

Hope this helped!

Answer:

Option B - The income earned in one month is $5.50.

Step-by-step explanation:

Given : At River Bank, checking account customers earn 0.75% interest a month on their account balances, pay no service fees for writing checks, and pay a monthly $2.00 financial charge.

To find : The income earned in one month on the checking account for a customer with an account balance of $1,000.

Solution :

Account balance of customer=  $ 1,000

Interest earned in checking account= 0.75%

Financial charge= $2.00

Therefore, Income earned in one month on the checking account  is given by 0.75% of 1,000 - $2

i.e, =\frac{0.75}{100}\times 1000 -2

=0.75\times 10 -2

=7.5 -2

=5.5

So, Option B is correct.

The income earned in one month is $5.50.
