Answer:
$10.00+ $2.25+ $2.25+ $2.25+$2.25=$18.90
$12.50+ $2.25+ $2.25= $17.00
$18.90-$17.00=$1.90 difference
Step-by-step explanation:
Step 1: Add $2.25 two times each for Martha and Kim will end up to the total of $4.50.
Step 2: Kim bought some pastries and a gift card for $12.50. Add $4.50 to the $12.50 and you get $17.00
Step 3: Martha bought more than two pastries and a gift card for $10. Add $4.50+$2.25+$2.25=$8.90 then you add the $8.90+$10.00=$18.90 total
Step 4: Martha and Kim both spent $2.25 each on pastries but does not specifically say how many she bought in the store.
Step 5: Subtract the price Martha and Kim paid to get the difference of money spent
