Answer:
216
Step-by-step explanation:
1. The total bill including sales tax is <u>$34.72</u>.
2. The amount the purchaser should pay the cashier is <u>$34.72</u>.
3. The denominations for the payment should be one $20 bill, one $10 bill, four $1 bills, and 72 cents (pennies).
<h3>How is the total cost determined?</h3>
The total cost payable to the grocery store cashier is the cost of the groceries plus the sales tax.
The cost for groceries = $32.75
Sales tax = 6%
Total cost = cost plus sales tax
= $34.72 ($32.75 x 1.06)
We can check the sum as follows:
Unit Bill Amount
1 $20 $20
1 $10 10
4 $1 4
Cents 0.72
Total $34.72
Thus, the grocery purchaser will be spending <u>$34.72</u>, including the sales tax.

After 200 years, 9.84 grams of Cesium would remain.
Let N represent the amount of substance after t years
The half-life of a cesium is 30 years., hence, this can be represented by exponential function:
where a is the initial value and b is the multiplier.
There were initially 1000g of the substance
a) The exponential model for this situation is:
b) After 200 years (t = 200), the amount of Cesium remaining is:
Hence after 200 years, 9.84 grams of Cesium would remain

How to graph 6x + 3y = 12
explanation:
Step 1: Find x intercept: substitute 0 for y: solve for x
• 6x + 3(0) = 12
• 6x = 12
• x = 2
Step 2: Then Find y intercept: also substitute 0 for x; solve for y
• 6(0) + 3y = 12
• 3y = 12
• y = 4
So plot x and y intercepts: ( 2,0 ) and ( 0,4 ) then draw a line through the points.

How to graph 3x + y = 5
explanation:
Step 1: Find x intercept: substitute 0 for y: solve for x
• 3x + 5(0) = 15
• 3x = 15
• x = 5
Step 2: Then Find y intercept: also substitute 0 for x; solve for y
• 3(0) + 5y = 15
• 5y = 15
• y = 3
plot x and y intercepts: (5,0 ) and ( 0,3) then draw a line through the points.
Hope this help:))
