Question

three siblings baked b brownies together this weekend. They threw away the 24 burned brownies and split the rest evenly, each taking home 10 brownies. how many did they bake

Answer 1

54 brownies

if there are 3 siblings and each takes home 10 brownies thats 30 brownies they split so 30 plus 24 would equal 54 brownies

Answer 2

They baked 54 brownies

Explanation:

We have a total of b brownies

Then we threw away 24

b-24

Then we split them between the 3 siblings

(b-24)/3

Everyone got 10

(b-24)/3 =10

Solve for b

(b-24)/3 =10

Multiply by 3 on each side

(b-24)/3 *3 =10*3

b-24 = 30

Add 24 to each side

b-24+24 = 30+24

b = 54

They baked 54 brownies
