Mr. hong is a rare coin collector he recently bought a coin valued $5400 it has been determined that the coin will increase in value by $30 each month mr Hong plans to sell the coin in 5 years name the quantities that change in this problem

$7,200

Quantities that changed in the problem are

1. The value of the coin

2. The time it took to appreciate to that value

Step-by-step explanation:

Current value = $5,400

Increase in value (monthly) = $30

In 5 years time, the value would increase by

(12*5) * $30 = $1800

Value in five years = current value + increase in value

Value in five years = $5400 + $1800

Value in five years = $7,200

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
