Answer:
Step-by-step explanation:
Let
x -----> the number of ice cream cones sold 5 years ago
Remember that
we know that
Sales 5 years ago, multiplied by the 30% increase should equal 18,000 ice cream cones.
so
The linear equation that represent this problem is
Solve for x
Divide by 1.3 both sides
$0.75 per pound 3/4 is 0.75
Answer:
A: Table W.
Step-by-step explanation:
A function for tables are where the X-input NEVER repeat.
Graph W. Doesn't have any repeating inputs on the x side
Y can repeat as much as the problem make wants but the x CAN NOT.
Hi there!
We can set up a ratio to model the problem...
540/3000 = x/100
Now, just cross multiply and solve for x.
54000 = 3000x
x = 18
Therefore, 18 percent of last semester's college costs was spent on books. Hope this helped and have a great day!
