Question

Suppose you buy flour and corn meal in bulk to make flour tortillas and corn tortillas flour cost $1.50 per pound and corn meal cost $2.50 per pound do you want to spend masking $25 on flour and corn meal but you need at least 6 pounds altogether Write a system of linear equalities

Answer 1

Answer:

1.50X+2.50Y=25

&

X+Y=6 are required systems

(Solution: X=16 and Y=-10)

Explanation:

》Total money that will be spent on flour and corn meal altogether(T)

=$25

》Since it is not mentioned that whether corn and flour are bought in same quantity or not, we will assume them of different quantity.

i.e.,Suppose

》X pound of flour is bought

&

》Y pound of corn is bought.

So,

》Cost of flour(F)=$1.50X

》Cost of corn(C)=$2.50Y

So total cost will be sum of cost of flour and corn altogether,

Writing it in equation(linear),

F+C=T

1.50X+2.50Y=25

Also,

Total pounds=6

ie,

X+Y=6
