Question

Please, someone, help me fill in this table. WHOEVER CAN HELP BEST WILL BE MARKED BRAINLIEST!!!

Answer 1

Half of the tuna sandwiches were on white bread

25% of the ham sandwiches were sold on brown bread

There were 20 more white bread sandwiches sold than brown bread.

To Find :

The two way equation

Solution :

Let The number of tune sandwiches = t

Let The number of ham sandwiches = h

let The number of white sandwiches = w

Let The number of brown sandwiches = b

So,

According to question

Number of white sandwiches sold = 20 + number of brown sandwiches sold

i.e  w = 20 + b              ..............1

half of  the tuna sandwiches were on white bread

i.e   = w          ............2

And

25% of the ham sandwiches were sold on brown bread

i,e  25 % of h = b

Or,  × h = b

Or,    b = 0.25 h             .........3

From eq 1 , 2 and 3 , we can get

      = 20 + 0.25 h            

Or,     = 20 +  × h

Or,    = 20 +

i.e    - = 20

Taking LCM

  = 20

i.e  2 t - h = 80

Hence, The equation which complete in two is 2 t - h = 80
