Question

Nandita earned $224 last month, $28 by selling cards and the rest by babysitting. Complete the equation to model the situation.

a)28+x=224
b)224−x=28
c) 224+x=28
d) x−28=224

Answer 1

The equation that models the amount Nandita earned from babysitting is 28 + x = 224. After subtracting 28 from 224, we find that she earned $196 from babysitting.

Step-by-step explanation:

Nandita earned money from selling cards and babysitting. She made a total of $224, out of which $28 came from selling cards. We need to find out how much she earned from babysitting. Let's represent the unknown amount she made from babysitting with the variable x. The correct equation to model this situation is:

28 + x = 224

To solve the equation, we subtract 28 from both sides:

x = 224 - 28

So:

x = $196

This means Nandita earned $196 from babysitting.
