1070.14 – Beetle and Rock

Tags:Problem Set 1Algebra IVisual

On the World Wide Web last week, as part of another order, I ordered a darkling beetle and a nice rock for him to live under. The beetle cost $1.00 more than the rock, and the two together cost $1.10 (before sales tax). What was the price of the rock?


The rock cost 5 cents; the beetle was $1.05.
