d.
Mikah's assets increased by $1,800.

Answers

Mikah's assets increased by $1,300 option (a) Mikah's assets increased by $1,300. is correct.

What is future value?

Based on an estimated growth rate, the future value is the amount that an asset will be valued at a future date. The computation assumes that at the start date, a fixed amount of cash is made available for investment and that it increases at a constant rate until the selected future date.

It is given that:

Mikah buys a new plasma television that is valued at $1,800.

He takes $300 from his savings account to use as a down payment and finances the rest.

As we know,

Net increase in asset = Purchase value of television − Value used from

savings account

Net increase in asset = $1600 - $300

Net increase in asset = $1300

Thus, Mikah's assets increased by $1,300 option (a) Mikah's assets increased by $1,300. is correct.
