Question

what is the answer Gregory can buy 4 pounds of wheat flour for $8 and 5 pounds of rye flour for $20. he has $12 to spend on a flour mixture. what is the linear equation

Answer 1

Since we have that by $8 he can buy 4 pounds of wheat fluor and with $20 he can buy 5 pounds of rye fluor, we will have the expression:

`y=(5)/(4)x`

That since we use the proportionality in order to determine the quantity of wheat fluor that is used with rye fluor.

`y=(1.25)x`
