write an expression to represent each total and then simplify it cost of 2 pens and 3 notebooks the note books costs 179 each nd the pens 289 each
It would help if you proofread your questions before you posted them. What units are you using? Are there supposed to be decimal places (e.g., 1.79, 2.89)?
3(1.79) + 2(2.89) = ?
3(1.79)+2(2.89)=11.15
To represent the total cost of 2 pens and 3 notebooks, you can use the following expression:
Total Cost = (Cost of 2 pens) + (Cost of 3 notebooks)
Now, let's calculate the cost of 2 pens:
Cost of 2 pens = (Number of pens) * (Cost per pen) = 2 * 289 = 578
Next, let's calculate the cost of 3 notebooks:
Cost of 3 notebooks = (Number of notebooks) * (Cost per notebook) = 3 * 179 = 537
Now, substitute these values into the original expression:
Total Cost = 578 + 537 = 1115
Therefore, the simplified expression for the total cost of 2 pens and 3 notebooks is 1115.
