Question

You owe your sister $100. You have already paid her $58. Write and solve an equation to represent

the amount of money that you still owe her. Define your variable.

Answer 1

Define x as the amount you owe your sister. The original debt is $100, and you've paid $58, so the equation is 100 - 58 = x. Solving it gives x = 42, hence you still owe $42.

Step-by-step explanation:

To represent the amount of money you still owe your sister after paying her $58 out of $100, you can define a variable to represent the remaining amount. Let's say x represents the amount of money you still owe. The original amount owed is $100, and you have paid $58, so the equation would be as follows:

100 - 58 = x

When you solve this equation, you subtract 58 from 100 to find the value of x:

100 - 58 = 42

x = 42

Therefore, you still owe your sister $42.
