Question

A caterer makes 3 extra sandwiches for every 20 sandwiches for a customer order. Write the ratio of ordered sandwiches to extra sandwiches. The caterer makes a total of 184 sandwiches for a customer. How many sandwiches did the customer order?

Answer 1

Caterer males 3 extra sandwiches for every 20 sandwiches. That means Caterer makes 23 sandwiches for every 20 ordered sandwiches. Therefore is ratio form we can write it,

23:20

Now we need to check if Caterer makes total 184 sandwiches for a customer then ordered sandwiches will be,

`23:20=184:x`

Where x represents the number of sandwiches ordered.

`23:20=184:x\\(23)/(20)=(184)/(x)`

Now we need to solve it for x;

`(23)/(20)=(184)/(x)\\x=(184X20)/(23)\\ x=160`

therefore ordered Sandwiches are 160.

Explanation:

Answer 2

8 sets of twenty sandwiches.

Explanation:

first you find the answer to 3 x __ = __ lets make the answer 24. That makes the other blank 8. Now subtract 24 from 184 and you should get 160. Divide 160 by 20 and you'll get how many set the customer ordered of twenty sandwiches. Multiply by twenty and you will get the whole amount they ordered.
