9) EASY POINTS WILL GIVE BRAINLIST TO BEST ANSWERS
Micaela spend $9 on a if a magazine cost $3, then how much was each eraser?
EXPLAIN
1(5) + 4(X) = 25
5 + 4X = 25
subtract 5 from both sides
4X = 25 – 5
4X= 20
divide both sides by 4
X = 20/4
x=5
Each eraser cost 5$
you bought a magazine for $5 and four erasers. you spent a total of $25.
Magazine cost: 5$ each
Eraser cost: X$ each
Total cost is the number of items (1 magazine) times the cost of each item (5$). We don’t know the cost of each eraser, so we represent that using a variable, X.
1(5) + 4(X) = 25
5 + 4X = 25
subtract 5 from both sides
4X = 25 – 5
4X = 20
divide both sides by 4
X = 20/4
X = 5
Each eraser cost 5$
