Problems to find price, quantity, cost

Price, quantity, and total cost

We often need to find the total cost of a purchase. Price is how much one item costs. Quantity is how many you buy. Total cost is how much you pay altogether. They are related by:

\text{price}\times\text{quantity}=\text{total}

. For example, a snack costs $2, you buy 3 → total

2\times 3=6

dollars.

Price ($ per item)

Quantity (items)

Total cost ($)

Formula:

\text{P}\times\text{Q}=\text{T}
