Answer:
340
Step-by-step explanation:
We can see in the sample that 18/50 people bring lunches to school. If we divide 18 by 50 we get 0.36 now we know that 36% of people bring their lunches in the sample. Now we take that number and multiply it by 942.
0.36*942= 339.12 which we can round to 340
I don't know if this is the right one but i hope this helps. this is how i learned it.
step 1=get variables on one side oof the equal sign by using inverse operation (add or subtract smaller variable)
step 2= get constants away from variable to the other side of the equal sign by using inverse operations (add or subtract constant)
step 3: isolate the variable using inverse operation (multiply or divide)
