Question 148075: The manual for your vehicle suggests that you use gasoline that is 89 octane. In order to save some money, you decide to use some 87 octane and some 93 octane in combination with the 89 octane currently in your tank in order to have an approximate 89 octane mixture. Assuming that you have one gallon of 89 octane remaining in your tank (our tank capacity is 16 gallons), how many gallons of 87 and 93 octane should be used to fill up your tank to achieve a mixture of 89 octane? In other words, how many gallons of 87 octane and 93 octane should be used to get 15 gallons of octane (why 15? 16 gallon capacity in tank and one gallon is already in there of 89 octane. You must find the solutions by both the process of substitution and by the process of elimination. Demonstrate both approaches.

Question 148868: I need an algebraic expression or formula for solving the following.
" A stamp collection consists of 3, 8, and 15 cent stamps. The number of 8 cent stamps is one less than triple the number of 3 cent stamps. The number of 15 cent stamps is six less than the number of 8 cent stamps. The total value of all the stamps is $2.47. Find the number of 8 cent stamps in the collection".
I was able to solve this using a chart displaying the multiples of 3, 8 and 15 side by side and calculating the sum of the different factors, of course starting by estimating the multiple of 3 first.
