, giving the house a new value.
(a) Fill in the blank to write the new value in terms of the old value.
Write your answer as a decimal.

New=value×Oldvalue


(b) Use your answer in part (a) to determine the new value.
Newvalue:$

(a) New value = 1.18 × 285,000 = 336,300 (rounded to the nearest hundred)

Answer: 1.18

(b) New value = $336,300 (rounded to the nearest hundred)

(a) To write the new value in terms of the old value, we can use the formula: New value = Old value + (Percentage increase/100) * Old value

In this case, the percentage increase is 18%. So, the formula becomes:

New value = Old value + (18/100) * Old value

Simplifying,
New value = Old value + 0.18 * Old value

(b) To determine the new value, we substitute the given Old value of $285,000 into the formula from part (a):

New value = $285,000 + 0.18 * $285,000

Solving this equation:

New value = $285,000 + $51,300

New value = $336,300

So, the new value of the house after the increase is $336,300.
