Torrance is buying presents for members of his family.He wants to spend $10 less on his brother than he spends on husband sister
,and six dollars more than twice the amounts he spends on his sister on his mother. If Torrance has $100 to spend,how much does he intend to spend on his brother?
Ok, so let x = the money that Torrance intends to spend on his brother. x + 10 = the money Torrance intends to spend on his sister 6 + 2(x + 10) = the money Torrance intends to spend on his mother So Torrance has $100 to spend.
Let's use all of this information and set up an equation. x + x + 10 + (6 + 2(x + 10)) = 100 2x + 10 + 6 + 2x + 20 = 100 4x + 36 = 100 -36 -36 ______________ 4x = 64 Divide 4 on both sides. You get $16. He intends to spend $16 on his brother.
