Step-by-step explanation: use a histograph
If this is for a better deal if you made the prices the same so instead of 5 for six itd be 50 for $60 and 8 for $10 would be 48 for $60 obviously 5 for 6 is the best choice. thats just how i was taught i hoped this helps
an equivalent expression is 5y+4
there is 3y which is y+y+y
so you have y+y+y+y+4+y
there are 5 y so it is 5y
then you have +4
5y+4
