You bought a magazine for $5 and four erasers. You spend a total of $25. How much did each eraser cost?
2 answers:
Answer:
$5
Step-by-step explanation:
Magazine cost: 5$ each
Eraser cost: X$ each
Total cost is the number of items (1 magazine) times the cost of each item (5$). We don't know the cost of each eraser, so we represent that using a variable, X.
subtract 5 from both sides
Hope this helps :)
Subtract magazine from total:
25 -5 = 20
Divide by number of erasers:
20/4 = 5
Each eraser cost $5
