##### Alex Wee's answer

Use X and Y to represent the number of \$10 and \$50 notes respectively. Form 2 equations using the information given. Since there are 4 more \$50 notes, the first equation should be Y(\$50)=X(\$10)+4. Second equation will be (\$50)(Y)+(\$10)(X)=\$380, this is to get the total amount of money. Sub equation 1 into equation 2. Solve for X, to get number of \$10 notes.
