6 points

#### Explanation:

Set up a ratio or proportion.

15/100 = ?/40

 15% = 15/100#

40 = the total just like 100 = the total

15% = the part just like the points scored = the part. so

$\frac{15}{100} = \frac{x}{40}$ now solve for x by multiplying both sides by 40

$\left(\frac{15}{100}\right) \times 40 = \frac{x}{40} \times 40$

$\frac{40}{40} \times x = x$ so

$\frac{15 \times 40}{100} = x$

$\frac{600}{100} = x$

$6 = x$
