Question

Jonah went on a vacation to Germany. He took $\$1800$ with him. After $3$ days, he had $\$1254$ left. How much did he spend in the first $3$ days?

Answer 1

Calculate amount of money spend in the first $3$ days:

The total money Jonah has is $\$1800$.

Money left after the first $3$ days is $\$1254$.

Money spent in the first $3$ days $=$ Total money $-$ Money left after first $3$ days.

Substitute the total money Jonah has as $\$1800$ and money left after the first $3$ days as $\$1254$.

Money spent in the first $3$ days is $1800-1254=546$.

Hence, Jonah spent $\$546$ in the first $3$ days.
