Joyce and tina had an equal amount of money. each day, joyce spent $24 and tina spent $28. when tina spent all her money, joyce still had $64 left. in how many days did tina spent all her money?

Joyce and Tina had an equal amount of money

Lets x = # of days they spent money

Joyce spent $24 still had $64 left = 24x + 64

Tina spent $28 a day and spent all her money, no left = 28x

Both has equal amount of money so

28x = 24x + 64

Subtract 24x from both sides

4x = 64

Divide both sides by 4

x = 16

Tina spent all her money in 16 days.

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.
