Marc saved $2,533 in January than in December.
Step by Step calculation.
Given the details below :
Salary In December =$3,650
In January, Increased by 12%
Marc saves 30% of $3,650 in December
New salary can then be calculated as :
= Initial salary * % increase / 100 + Initial salary
= 3,650 * 12 / 100 + 3,650
= 3,650 * 0.12 + 3,650
= 4,088
The difference will now be
= 4,088 - 3650
= $438
Since Marc saves in December 30% of $3,650

= $1,095
Saves in January
= 1,095 + 438
