Answer:
Devin will donate $67.5 to charity.
Step-by-step explanation:
Given:
Devin made 30 custom t-shirts to sell.
He will donate 1/8 0f his total sales to a local charity.
He sold all 30 t-shirts for $18 each.
Now, to find the amount Devin donate to charity.
Total number of t-shirts = 30.
Each t-shirts sold at = $18.
So, total amount of 30 t-shirts sold:
[tex]30\times 18[/tex]
[tex]=\$540.[/tex]
As, Devin will donate [tex]\frac{1}{8}[/tex] of his total sales to a local charity.
Now, to get the amount he will donate to charity:
[tex]\frac{1}{8} \ of\ \$540\\\\=\frac{1}{8} \times 540\\\\=\frac{540}{8}\\\\=\$67.5.[/tex]
Therefore, Devin will donate $67.5 to charity.
