The sales price of all brooms = $78.30
Sales tax = 8%
Target question => what is the price of 1 broom excluding sales tax?

Statement 1 => The sales tax on each broom was $1.16
Let the price of 1 broom without tax = x
The total price of 1 broom = x + 8% of x
= x + 0.08x = 1.08x
Given that sales tax = $1.16
0.08x = $1.16
x = 1.16/0.08 = 14.5
Price of 1 broom excluding sales tax = $14.5
Statement 1 is SUFFICIENT

Statement 2 => Sue bought 5 brooms at Gigamart
Therefore, 5 brooms = $78.30
1 broom (with sales tax) = 78.30/5
= $15.66
Let price of 1 broom without tax = x
The total price of 1 broom = x + 8% of x
= x + 0.08x = 1.08x
$$Therefore,\$15.66=1.08x$$
$$x=\frac{15.66}{1.08}=14.5$$
Price of 1 broom excluding sales tax = $14.5

Since each statement alone are SUFFICIENT
Answer = D
