The population of Weston is 4320. The town’s records show that 45 percent of the population are males, and 2 3 23 of these males

lbvjy [14]

Answer:

In Weston 1,296 males are married

Step-by-step explanation:

step 1

Find out the number of males

Multiply the total population by 45%

$4,320(0.45)=1,944\ males$

step 2

Find out the number of males that are married

Multiply the number of males by 2/3

$\frac{2}{3}(1,944)=1,296\ males\ married$

therefore

In Weston 1,296 males are married
