Answer:

$25.31

Step-by-step explanation:

Tim saves $45.17 each month for 3 months, so he saves a total of 45.17 3 times = 45.17 * 3 = 135.51

total needed to save = amount Tim saves + amount Tom needs to save

amount Tom needs to save = total needed to save - amount Tim saves

= 211.44 - 135.51

= 75.93

Tom needs to save x amount of money each month for 3 months, or x 3 times for a total of 75.93, so 3*x = 75.93

divide both sides by 3 to isolate x

x = 25.31
