Work Step by Step
Multiply the cost per member times the number of members to find the total cost. $30\times95=2850$ To solve using mental math, use the distributive property to restate the problem. $30\times95=30(100-5)$ Mental math tells us that $30\times100=3000$ and $30\times5=150$. Use mental math to subtract 150 from 3000, giving us $2850.
