Question

Flour costs $0.80 per pound and sugar costs $0.50 per pound. An order of flour and sugar weighs 15 pounds and costs $9.00. Make a system of equations?
Please help I really need your help.

Answer 1

Answer: $x+y=15$

$0.80x+0.50y=9$

Step-by-step explanation:

Let x be the amount of flour and y be the amount of sugar ordered.

Since, the order of flour and sugar weighs 15 pounds.

Therefore, $x+y=15$

Also, Flour costs $0.80 per pound and sugar costs $0.50 per pound.

The cost of ordered flour=$0.80x

The cost of ordered sugar=$0.50y

Now, the total cost of the order= $0.80x+0.50y=9$

Hence, for the given situation the system of equations is:-

$x+y=15$

$0.80x+0.50y=9$
