She was 22 when she had triplets
so if the triplets are 12 then just add
22+12=34
or when she had Mia she was 18
if Mia is 16 then add
18+16=34
Also, she had another child at 23
if the child is 11 then add
23+11=34
Hope it helps! :)
9x135 = 1,215
10x135 = 1,350
11x135 = 1,485
Therefore, your answer would be 10.
N=5
solve it the same way you would a proportion
4+48=52
if you divide 52 by 4 you should get 13.
this means michael paid 13 dollars per pizza :)
