Answer:

Step-by-step explanation:
we know that
The equation of a exponential function is of the form

where
a is the initial value or y-intercept
b is the base of the exponential function
In this problem we have
----> the y-intercept is given
substitute

we have the other ordered pair (1,10)
substitute the value of x and the value of y and solve for b


substitute

Answer:
Her grocery bill was <u>$4.62</u>.
Step-by-step explanation:
There is some mistake in question so the correct question is:
Sherry bought 6 apples at 43¢ per apple. She then bought 4 oranges at 51¢ per orange. How much was her grocery bill?
Now, to find the grocery bill.
As the units are given:
<em>43¢ per apple and </em>
<em>51¢ per orange.</em>
$1 = 100¢.
So, the cost of 6 apples = 
Thus, the cost of 6 apples = $2.58
And the cost of 4 oranges = 
Thus the cost of 4 oranges = $2.04
Now, to get the total grocery bill we add the cost of apples and oranges:


Therefore, her grocery bill was $4.62.
Answer:
