Brown has his own bakery. he baked 5 cakes per day. due to the occasion of christmas, he started to bake 12 cakes per day. in the whole christmas week how many cakes will he bake

7 times 12= 84 because there are 7 days in the week so multiply the 7 by the 12 cakes made each day of the week

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)
