Answer:
$395,800
Explanation:
If the Carson's saved up $39,580, and their dream house is 10 times as much as they saved, set up the following problem:
x = 39,580 · 10, where x represents the cost of their dream house.
The reason we set this up is because, we know that they saved an amount and the cost of the dream house is 10 times as much as their saved amount, so all we had to do was multiply their saved amount by 10 (the keyword "times" indicates multiplication.)
Now let's solve:
x = 395,800
Their dream house costs $395,800.
