at the market, a pear cost b cents&an apple cost 7 cents less than a pear.Mrs Ravi bought 4 pears&an apple.Find the total amount Mrs Ravi paid in terms of b. Help me!
cost of pear = b
cost of apple = b-7
amount paid = 4b + b-7 = 5b-7
Let's break down the problem step-by-step.
1. Let's assume the cost of a pear is b cents.
2. According to the given information, the cost of an apple is 7 cents less than the cost of a pear, which means the apple costs (b - 7) cents.
Now, we need to find the total amount Mrs. Ravi paid for 4 pears and 1 apple.
3. The cost of 4 pears would be 4 * b cents, which can be written as 4b cents.
4. The cost of 1 apple would be (b - 7) cents.
5. To find the total amount, we need to add the cost of pears and the cost of the apple: 4b + (b - 7) cents.
Therefore, the total amount Mrs. Ravi paid is (4b + b - 7) cents, which can be simplified to 5b - 7 cents.
To find the total amount Mrs. Ravi paid in terms of b, we need to calculate the cost of each fruit separately and then add them together.
Let's break it down step by step:
1. We know that a pear costs b cents. So the cost of 4 pears would be 4b cents.
2. According to the information given, an apple costs 7 cents less than a pear. So if a pear costs b cents, an apple would cost (b - 7) cents.
3. Mrs. Ravi bought 4 pears and 1 apple. Therefore, the total cost of the pears would be 4b cents, and the cost of the apple would be (b - 7) cents.
4. To find the total amount Mrs. Ravi paid, we need to add the cost of the pears and the apple together.
Total amount = (Cost of pears) + (Cost of apple)
= 4b + (b - 7)
= 5b - 7
So the total amount Mrs. Ravi paid in terms of b would be 5b - 7 cents.
