How many calendars did the 1st and 2nd period classes sell on average per week? Write and solve a multiplication equation.

4 = c x 183

So I say it's 45.75 on average.

Step-by-step explanation:

but it says before that question ''FUNDRAISING A school is raising money by selling calendars for $20 each. Mrs. Hawkins promised a party to whichever of her English classes sold the most calendars over the course of four weeks. Use the table to answer Exercises 18–20'' so wouldn't you divide the calendars to 4? because this is what the students made in 4 weeks so if you divide by 4 you will get completely different answers... and 60 divided by 4 is 15 and 123 divided by 4 is 30.75. Which is 45.75 added together. as for that multiplication equation, I say it 4 = c x 183, which if you do 183 (the total for both periods) divide by 4, you will get 45.75 (rounded up will be 46, but I think you should keep it as 45.75 because you're not really asked for simplifying) So I say its 45.75 for average.

I’m having a hard time understanding your question

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
