Question

The total amount of sap y (in ounces) collected from a tree after x weeks is represented by the equation y=3x+8. How much more total sap is there after 5 weeks than 4 weeks

Answer 1

Answer: 3 ounces

Step-by-step explanation: it is a substitution question

let x=5 which represents the number of weeks

we substitute into the equation y=3x+8

we get y=3 *5+8=23 ounces of sap after 5 weeks

We now let x=4 for 4 weeks and substitute into the equation

y=3*4+8=20

There are 3 more ounces of sap after 5 weeks than 4 weeks
