Question
Five pounds of rice at a store cost $6.50. Rice seasoning cost $1.00 per bottle.
Use the Ray tool to graph the total cost of rice and bottle of seasoning, C, vs pounds of rice, p, at this store.

What is the answer?
Okay I have a graph. On the bottom it says Rice (Ib) the numbers are 1 2 3 4 5 6 7 8 9 10. Now on the side the number are like 0.5 then 1 then 1.2 then 2.5 the 3 and so forth it is a pattern of the decimals.

To calculate the total cost, \( C \), of purchasing \( p \) pounds of rice and a bottle of seasoning, we can use the cost information provided:
1. The cost of rice is $6.50 for 5 pounds. Therefore, the cost per pound of rice, \( r \), is:
\[
r = \frac{6.50}{5} = 1.30 \text{ dollars per pound}
\]
2. The cost of one bottle of seasoning remains constant at $1.00.
The total cost \( C \) as a function of pounds of rice \( p \) can be expressed as:
\[
C(p) = 1.30p + 1.00
\]
### Graphing the Equation
1. **X-axis** (Rice in pounds, \( p \)): This ranges from 1 to 10 pounds.
2. **Y-axis** (Total cost, \( C \)): We need to calculate the total cost for different values of \( p \).
### Calculations for Different Values of \( p \):
- For \( p = 1 \):
\[
C(1) = 1.30(1) + 1.00 = 2.30
\]
- For \( p = 2 \):
\[
C(2) = 1.30(2) + 1.00 = 3.60
\]
- For \( p = 3 \):
\[
C(3) = 1.30(3) + 1.00 = 4.90
\]
- For \( p = 4 \):
\[
C(4) = 1.30(4) + 1.00 = 6.20
\]
- For \( p = 5 \):
\[
C(5) = 1.30(5) + 1.00 = 7.50
\]
- For \( p = 6 \):
\[
C(6) = 1.30(6) + 1.00 = 8.80
\]
- For \( p = 7 \):
\[
C(7) = 1.30(7) + 1.00 = 10.10
\]
- For \( p = 8 \):
\[
C(8) = 1.30(8) + 1.00 = 11.40
\]
- For \( p = 9 \):
\[
C(9) = 1.30(9) + 1.00 = 12.70
\]
- For \( p = 10 \):
\[
C(10) = 1.30(10) + 1.00 = 14.00
\]
### Summary of Points to Plot:
- (1, 2.30)
- (2, 3.60)
- (3, 4.90)
- (4, 6.20)
- (5, 7.50)
- (6, 8.80)
- (7, 10.10)
- (8, 11.40)
- (9, 12.70)
- (10, 14.00)
### Plotting the Graph
- Plot these points on your graph, where the x-axis (pounds of rice) ranges between 1 and 10 and the y-axis (total cost) includes values from about 2.20 to 14.00.
- Connect the points with a straight line, since the relationship is linear.
### Conclusion
The graph \( C \) vs. \( p \) will be a straight line starting from (1, 2.30) and increasing linearly to (10, 14.00). The slope of the line represents the cost per additional pound of rice, which is $1.30, while the y-intercept (the cost when no rice is purchased) is $1.00, which is the cost of the seasoning.
