Jessica is having a sweet tooth and bought 10 chocolate bars, 10 packs of gummy bears, and 20 bags of chocolate chips. Her total rang up to $150. If the cost of a pack of gummy bears is $2 and a bag of chocolate chips costs $5, how much does 1 chocolate bar cost?
Let's be accurate as possible and think first.
3
The gummy bears cost 10 * 2 = $20.

The chocolate chips cost 5 * 20 = $100.

The total cost for these two is 100 + 20 = $120.

The chocolate bars in total cost 150 - 120 = $30.

A single chocolate bar costs 30 / 10 = $3.

.

Thus, the answer is 3
