• A. 567 cups
• B. 578 cups
• C. 587 cups
• D. 487 cups

Answer 1

The correct option is C 587 cups

Number of boxes Jax has $=5$
Number of cups in each box $=100$
Total number of cups Jax has $=100+100+100+100+100=500$
Number of boxes Jane has $=8$
Number of cups in each box $=10$
Total number of cups Jane has $=10+10+10+10+10+10+10+10=80$
Number of cups Jane's friend has $=7$
Total number of cups they have $=500+80+7=587$
$\begin{array}{cccc}& \text{H}& \text{T}& \text{O}\\ & 5& 0& 0\\ +& & 8& 0\\ +& & & 7\\ & 5& 8& 7\end{array}$
Hence, they have $587$ cups in total.
