Money made for a sandwich shop was 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?
120,000
simplest way: by ratio
2000:120000=x:180000
2/120 = x/180000
120x = 360 000
x = 3000
second way
let revenue be R, let Advertising cost be A
then R = kA, where k is a constant
replace the given case where R=120000 and A = 2000
120000=k(2000)
k = 60 000
so R = 60 000A
sub 180000 for R....solve ... A=3000
To find out how much the owner is spending on advertising, we can use the fact that the money made by the sandwich shop is directly proportional to the advertising budget.
We are given that when the owner spent $2000 a month on advertising, the revenue was $120,000.
Let's call the advertising budget A and the revenue R. We can represent the relationship between A and R as R = kA, where k is a constant.
Using the given values, we can substitute A = 2000 and R = 120,000 into the equation:
120,000 = k * 2000
Simplifying, we find:
k = 120,000 / 2000
k = 60
So our equation becomes:
R = 60A
Now we need to find the advertising budget when the revenue is $180,000. Let's call this new advertising budget x.
Substituting R = 180,000 into the equation, we have:
180,000 = 60x
Solving for x, we find:
x = 180,000 / 60
x = 3000
Therefore, the owner is currently spending $3000 on advertising.
