Answer:
We need 29 more $10 donations to complete $600 amount.
Step-by-step explanation:
Amount of money asked for donation = $10
Total amount of donation needed = $600
Amount of donation collected = $310
Amount of donation to be collected = $600 - $310 = $290
Let the number of $10 donation needed be x.
[tex]x\times \$10=\$290[/tex]
[tex]x=\frac{\$290}{\$10}=29[/tex]
We need 29 more $10 donations to complete $600 amount.
