• A. $789$
• B. $788$
• C. $987$
• D. $798$

Answer 1

The correct option is A $789$

Number of banana baskets Jane has $=7$
Number of bananas in each basket $=100$
Total number of bananas Jane has $=100+100+100+100+100+100+100=700$
Number of banana baskets Jax has $=8$
Number of bananas in each basket $=10$
Total number of bananas Jax has $=10+10+10+10+10+10+10+10=80$
Number of bananas Jax's friend has $=9$
Total number of bananas they have $=700+80+9=789$
$\begin{array}{cccc}& \text{H}& \text{T}& \text{O}\\ & 7& 0& 0\\ +& & 8& 0\\ +& & & 9\\ & 7& 8& 9\end{array}$
Hence, they have $789$ bananas in total.
