Answer:
15
Step-by-step explanation:
Fiona (F) = Sushi (S)
Malachy (M) = 7 Fiona (F)
M = F + 90
F + 90 = 7F
6F = 90
F (Fiona) = 15
S (Sushi) = 15
check: Malachy (M) = 15 * 7 = 105
M-F = 105 - 15 = 90
2×3=6
or 6×5=30
Theres a lot!
74
So, what you have to do s 7.4 times 10 and then you get the anwser 74.
6x9+6+9 = 69
