Question

Mario invested $475 in $45 and $25 stock shares. The number of $25 shares was 5 less than 3 times the number of $45 shares. How many of each type of share did he buy?

Answer 1

Step-by-step explanation:

let no. of $45 shares be 'y'

no. of $25 shares = 3y - 5

total investment= $475

45y + 25(3y - 5) = 475

45y + 75y - 125 = 475

120y = 600 => y = 5

no. of $45 shares = 5 & no. of $25 shares = 3(5) - 5 = 10
