The revenue for a sanwich shop is directly proportional to its advertising budget. When the owner spent $2000 a month on advertising,the revenue was $120,000. If the revenue is now $180,000, how much is the owner spending on advertising?
Please Help!!
Set up a proportion.
$2,000 : $120,000 :: x : $180,000
To solve this problem, we need to set up a proportion to find the amount the owner is spending on advertising now.
Let's set up the proportion:
$2,000 : $120,000 :: x : $180,000
To solve this, we can use the concept of cross-multiplication.
Cross-multiplication involves multiplying the numerator of one side by the denominator of the other side, and vice versa.
So, we have:
($2,000) * ($180,000) = ($120,000) * (x)
Multiplying these values, we get:
$360,000,000 = $120,000 * x
Now, we can solve for x by dividing both sides of the equation by $120,000:
($360,000,000) / ($120,000) = x
Dividing these values, we find:
x = $3,000
Therefore, the owner is currently spending $3,000 on advertising.
