a company advertises on two websites. each website charges a different amount based on the number of clicks on he advertisement. the table shows the number of clicks on each website and the total cost for each of two days. cost of website advertisements day number of clicks on website 1 number of clicks on website 2 total cost (dollars) monday 15 29 94.15 tuesday 25 29 121.15 what is the cost per click on website 1? a $1.85 b $5.38 c $2.20 d $2.70
Answer
Explanation:
Step1: Set up equations
Let $x$ be the cost - per - click on Website 1 and $y$ be the cost - per - click on Website 2. For Monday: $15x + 29y=94.15$. For Tuesday: $25x + 29y=121.15$.
Step2: Subtract the first equation from the second
$(25x + 29y)-(15x + 29y)=121.15 - 94.15$. $25x+29y - 15x - 29y=27$. $10x=27$.
Step3: Solve for $x$
$x=\frac{27}{10}=2.7$.
Answer:
D. $2.70$
