Question

of the 50 tables in a resturant, 40% seat 2 people. The remaining tables seat 4 people. How many seats are there in the restaurant

Answer 1

there are 160 people in the restaurant



40%of 50 is 20:

`(50)/(100) = (x)/(40) \\ x = (40 * 50)/(100) = (2000)/(100) = 20`


the rest of the tables seat 4 people:

`50 - 20 = 30`

so the number of people in the restaurant is 160

`20 * 2 = 4 0 \\ \\ 30 * 4 = 120 \\ \\ 120 + 40 = 160`




good luck
