An electricity company estimates that Daryl will spend £440 on electricity next year. An administration charge of 15% is added. Daryl wants to pay in four equal instalments throughout the year, How much should each payment be?

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)
