678 + 303 = 981
Here are a few examples to get you started:
600 + 300 = 900
<span>78 + 3 = 81 </span>
<span>900 + 81 = 981
</span>Here's another one:
678 = 600 + 70 + 8
<span>303 = 300 + 00 + 3 </span>
<span>Add the ones place = 11 </span>
<span>Add the tens place = 70 </span>
<span>Add the hundreds place = 900 </span>
<span>Now add 900 + 70 + 11 = 981</span>
Hope this helps! :-)
The cost of each hamburger is $ 3.5
<em><u>Solution:</u></em>
Given that, Daniel purchased one hotdog for $2.50 and three hamburgers
