Suppose you buy flour and cornmeal in bulk to make flour tortillas and corn tortillas. flour costs $1.50 per pound and cornmeal costs $2.50 per pound. you want to spend less than $25 on flour and cornmeal, but you need at least 6 pounds altogether.

The quantity of flour and cornmeal is at least 6 pound and The cost of flour and cornmeal altogether is $ 14.50

Step-by-step explanation:

Given as :

The cost of flour = $1.50 per pound

The cost of cornmeal = $2.50 per pound

The cost spend on flour is less than $25

The quantity of flour and cornmeal together = 6 pound

Let the quantity of flour = 0.5 pound

So, The cost of 0.5 pound flour = $1.50 × 0.50 =$ 0.75

Let The quantity of cornmeal = 5.5 pound

So, The cost of 5.5 pound cornmeal = $2.50 × 5.5 =$ 13.75

Thus The quantity of flour and cornmeal together = 0.5 + 5.5 = 6 pound

And The cost of flour and cornmeal together = $ 0.75 + $ 13.75 = $ 14.50

Hence, The quantity of flour and cornmeal is at least 6 pound and The cost of flour and cornmeal altogether is $ 14.50   Answer
