Example 1:
martha bought pastries and a gift card for her friend's birthday. she bought pastries for $2.25 each and the gift card for $10. her friend kim
also bought some pastries for $2.25 each and a gift card for $12.50.
for how many pastries will the amount spent by martha and kim be the same?

$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

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
