A soft drink manufacturer produces 3408 cans in an 8-hour day. Cans are packaged 24 to a case. How many cases are produced each week? each month? (Assume one week is 40 hours, and one month is four weeks.)

we know that

Part a) How many cases are produced each week?

A soft drink manufacturer produces
3408 cans in ------------------>  8-hour day
X cans-------------------------> 40 hour (week)
X=40*3408/8---------> X=17040 cans/week

if 1 case ------------------> 24 cans
X case----------------------> 17040 cans
X=17040/24---------> X=710 cases

then answer Part a) is 710 cases for week


Part b) How many cases are produced each month?

A soft drink manufacturer produces 
17040 cans in ------------------>  1 week
X cans-------------------------> 4 week
X=4*17040---------> X=68160 cans/ month

if 1 case ------------------> 24 cans
X case----------------------> 68160 cans
X=68160/24---------> X=2840 cases

then answer Part b) is 2840 cases for month
