Solving a Ratio Problem: Lucas's Toy Figurine Savings Goal

Let's assume that Lucas saved $x on Monday. Therefore, he saved 5x from Tuesday to Sunday.
After saving $x on Monday and $8.20 on Tuesday, he was 70% away from his targeted amount. This means that the total amount he targeted to save was (x + $8.20) / (1 - 0.70).\nSimplifying the expression, we get (x + $8.20) / 0.30 = (10x + x + 8.20) / 0.30 = 11x + 27.33.\nSince the amount he saved for the rest of the week (Tuesday to Sunday) is 5x, the total amount he targeted to save is 5x + 11x + 27.33 = 16x + 27.33.\nTherefore, the amount he targeted to save is $16x + $27.33.
