3. Emma has \( \$ 95.20 \). She buys a new skateboard for \( \$ 64.99 \). Can she buy a helmet for \( \$ 34.99 \) ?

After purchasing the skateboard for \( \$ 64.99 \), Emma's remaining balance is \( \$ 95.20 - \$ 64.99 = \$ 30.21 \). Unfortunately, the helmet costs \( \$ 34.99 \), which is more than her remaining balance. So, no, she cannot buy the helmet after getting the skateboard. To avoid similar situations, it's a good idea for Emma (or anyone) to keep track of their expenses by writing a simple budget. Being aware of how much each item costs before shopping helps prevent surprises like this one! Next time, she can plan her purchases better or look for discounts.
