Answer:
Step-by-step explanation:
<u>Cost of each item:</u>
- Pencils = 2p
- Calculators = 25c
- Rulers = 4r
<u>Total cost as expression:</u>
Answer:
The answer should be D. 102.4
substitute the values for the letters
2(-17) = -34
3(-4) = -12
-34 - -12 = -34 +12 = -22
-22 is not greater than 12 so it is not a solution
We have A number of apples, each purchased at 15 cents.
We can, thus, calculate the total cost of apples as follows:
Total cost of apples = 15A cents
We have B number of bananas, each purchased at 10 cents.
We can, thus, calculate the total cost of bananas as follows:
Total cost of bananas = 10B cents
Now, the total cost of purchases can be calculated by adding the amount paid for both types (apples and bananas) as follows:
Total cost = cost of apples + cost of bananas = 15A + 10B cents
