Answer:
$2.00 is the original price
Step-by-step explanation:
Step 1:
Turn 25% into a decimal which makes it 0.25
ex. 50% would be 0.50, 5% would be 0.05 etc.
Step 2:
Put the numbers into this formula: Original Price (x) - Percent Off times Original Price = Sales Price
x - 0.25x = 1.50 this is basically 1x - 0.25x = 1.50 so,
Solving the left side of our equation gives us 1x - 0.25x = 0.75x
so now you have: 0.75x = 1.50
Step 3:
Divide both sides by 0.75 which gets x by itself and gives us the original price which is $2.00
Answer:
The data from the previous table is plotted to the right. The distance the boat traveled is on the x-axis, and the vertical position of the barnacle is on the y-axis.
The graph follows the pattern.
This is the pattern for a function.
The amplitude is
.
The vertical shift is
.
An equation for this graph is y = .

Answer:
Option 2
Step-by-step explanation:
Let's say that Phalicia opens her savings account one year (12 months) before she goes to college.
With Option 1, she would have saved 300 + 50 * 11 = $850. We do 50 * 11 and not 50 * 12 because she deposits $50 for 11 months, not 12.
With Option 2, she would have saved 5 * 3¹¹ = $885735. Note that we do 3¹¹ and not 3¹² because 5 is being tripled 11 times.
Obviously, she should choose Option 2 because she saves A LOT more money.
Additionally, we can notice that Option 1 is an example of an arithmetic sequence whereas Option 2 is an example of a geometric sequence. Their explicit formulas would be aₙ = 50n + 250 and aₙ = 5 * 3⁽ⁿ⁻¹⁾ respectively.
