Question

at a festival, a woodworker has 30 wooden boxes on display. They are worth a total of $3100 at retail prices. The smaller size sell for $80, and the larger size sellf for $150. How wany of each size box are on display?          Use let statements

anonymous · Answer

A "let statement" is just telling you what your variables mean.
Like let $s$ = the number of smaller boxes. Or let $l$ = the number of larger boxes.

anonymous · Answer

i know but i dont know what the equation would be

anonymous · Answer

It's a system of linear equations.
There are 30 boxes total.
So $l + s = 30$

anonymous · Answer

Then you know that the smaller boxes sell for 80 and the larger boxes sell for 150, and the total value of them is 3100.
So $80s + 150l = 3100$

anonymous · Answer

yes i did that but i dont know how to do it

anonymous · Answer

Ok, do you know how to solve systems of linear equations?

anonymous · Answer

nope

anonymous · Answer

At all? They gave you a problem involving a system of linear equations without telling you how to solve them?
