Respuesta :

If he spent 3/7 of his money on souvenirs, it means that he had kept 4/7 of his money...

4/7 * M = 16

7 * 4/7 * M = 16 * 7

4M = 112

M = 112/4

Therefore:

M = 28

Answer:

Joshua had $28 to begin with but spent $12 of his money.

We can check if this is the correct result by multiplying $28 by 3/7.

3/7 * $28

= ($28*3)/7

= ($84)/7

= $12
