Answer:
[tex]x = 7[/tex]
Step-by-step explanation:
We have:
- purchased x number of items
- at a unit price of $8/item
We know that the:
- total cost of these items was $56.
We can model this situation with an equation to solve for x:
[tex](x \text{ items}) \cdot \dfrac{\$8}{\text{item}} = \$56[/tex]
↓ canceling the
- "items" unit (because it's in the numerator and denominator)
- dollar unit (because it's on both sides)
[tex]8x = 56[/tex]
↓ dividing both sides by 8
[tex]\boxed{x = 7}[/tex]
So, we purchased x = 7 items.
