Explanation:

Step1: Calculate total available funds

$\$347.21 + \$162.80 = \$510.01$

Step2: Find remaining amount needed

$\$637.95 - \$510.01 = \$127.94$

Step1: Calculate total allowed distance

$50000 - 36026.3 = 13973.7$ km

Step2: Find one-way max distance

$\frac{13973.7}{2} = 6986.85$ km

Step3: Compare to trip distance

$6986.85 > 6725.2$

Step1: Calculate total spent amount

$\$63.18 + \$72.35 + \$47.25 = \$182.78$

Step2: Find remaining money

$\$230.00 - \$182.78 = \$47.22$

Step1: Calculate total cost of items

$\$6.99 + \$9.99 + \$3.99 = \$20.97$

Step2: Compare to Kate's money

$\$20 < \$20.97$

Answer:

$\$127.94$
