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
