Answer:
1
Step-by-step explanation:
let G be the number of grand croisssants, and P the number of petit croissants :
we have that 1 ounce of flour and 2 ounces of butter result in one G.
additionally, we have that 1/4 ounce of flour and 1/3 ounce of butter result in one P.
Ralph has 4 ounces of flour and 6 ounces of butter, If he bakes more than 1 G then he will never use all of his ingredients!, let's see:
1 G:
he now has 3 ounces of flour, and 4 ounces of butter,
now we need to figure out how many P's we would obtain with such amounts:
let x be the number of P's
which is reasonable, Ralph can bake 12 P's,
now with more than 1 G:
2G:
Ralph has now 2 ounces of flour and 2 ounces of butter, now we have to figure out that x is the same using the remaining ingredients
This is impossible.
3G:
he runs out of butter.
There is the answer, he is able to bake 1 grand croissant and 12 petit croissants
