Helen spent $145 for shoes. This was $55 more than twice what she spent for a bag. How much was the bag?
marin [14]

Answer:

45 DOLLARS

Step-by-step explanation:

For these kind of problems, write an equation to figure out the answer.

55 + 2x = 145

x represents the bag cost

145 is the shoe cost

Take out the constant, which is 55, from both sides. A constant is a useful term you should learn.

The result is: 2x = 90

Divide 2x by 2, to get x, which is the bag cost, by itself.

Result: x= 45

Since x is the bag cost, the bag costs 45 dollars
