Because has 12 more than cece. dave has $3 less than cece. cece has $10

12 + 10(Cece) = $22(Because)
10 - 3 = $7(Dave)

Cece has 10 and if Because has 12 more that means:
10+12=22
Because has $22

Cece has 10 and if Dave has 3 LESS THAN her that means:
10-3=7
Dave has $7

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)
