<span>Given that there are 50 campers at day camp and 10
counselors.
The ratio of campers to counselors as a fraction is given by
.
Using equivalent fractions we have
.
Thus, the related rate and unit
rate to the ratio of campers to counselors is given by
.
The unit rate indicates that for every counselor, there are 5 campers.</span>

3 * 16 - 28 + 9
= 29
