VARIABLE EQUATIONS & INEQUALITIES - 2/5

Ted and Katie have saved up a total of $94.00. Ted has saved $6 less than 4 times as much as Katie. How much has Katie saved?

Answer 1

Let K = Katie's savings. Then Ted has 4K − 6. Their total is K + (4K − 6) = 94.

So 5K − 6 = 94 → 5K = 100 → K = 20.

Katie saved $20. (Ted saved $74.)
