Denzel has 3 2/5 boxes of party favors. one full box contains 15 bags of favors and each bag has 3 favors in it. in addition to this he has 7 extra party bags that are not in bags or boxes. select the correct operation to model a numerical expression for the total number of party favors. 3 2/5__15__3__7

So first we multiply

3 2/5 x 15 =
17/5 x 15/1 =
255/5 = 51

Then, we multiply it by 3

51 x 3 = 153 + 7 x 3 = 153 + 21 = 174

So the expression should be: 3 2/5 x 15 x 3 + 7

First, think of what you know. you know that the number t the end of the equation will need to be subtracted because it is the money he lost from buying the lawn mower. and your first two weeks have negative profit, so that tells you that c and d are wrong. now you can plug any of the weeks into a and b to see which one works. i'll start with plugging week 1 into a.this isn't right because it says your answer for week one should be -90.so now we need to try the same thing with b.this one got you the right answer, (sometimes if you only check with one of the weeks multiple will work so you need to check with more of the weeks, but it worked out fine here)this means that b is the correct answer.let me know if you need more clarification. i hope this : )
