A pack of potato chips costs a dollar and a half. A teacher buys enough packs for 10 students to have one pack each. How much did she pay in total?
To solve this problem, we'll follow these steps:
Now, let's work through each step:
Step 1: The problem gives us the cost per pack is \1.50 \) and the number of packs is .
Step 2: We'll use the formula: Total Cost = (Cost per Pack) (Number of Packs)
Step 3: Plugging in our values, we get: Total Cost =
Therefore, the teacher paid a total of \15\).
\( 15
\( \text{0}.07\times10= \)
You're finding the total cost for multiple items. If each pack costs 1.50, which is multiplication: $1.50 × 10.
When multiplying by 10, move the decimal point one place to the right. So 15.0 or simply $15.
Both are correct! 15.00 represent the same amount. In money problems, you can write either form.
The same rule applies! Multiply normally and count decimal places. For example: 10.00 (2 decimal places in $1.25, 0 in 8, so 2 total).
Use division to check! Divide your total by the number of items: 1.50. This should equal the original cost per pack.
