Two families have a garage sale together the entire garage sale brought in $1640 one family made $182 more than twice as much of
ioda

Answer:

On the sale of garage One family made $1154 and Second family made $486

Step-by-step explanation:

Given:

Two families have a garage sale together the entire garage sale brought in $1640

Total Cost = $1640

Let the Second made be x

Also given one family made $182 more than twice as much of the second family

One family made = 182+2x

Now Total cost is equal to sum of One family and Second family.

Hence framing in equation form we get;

x+182+2x=1640

Now solving the equation we get;

3x+182=1640\\3x=1640-182\\3x= 1458\\x=\frac{1458}{3}= \$486

Hence,

Second Family made on sale of garage = $486

One Family = 182+2x=182+2\times486 = 182 + 972 = \$1154

Hence One Family made on sale of garage = $1154
