Ten baseballs and four ping-pong balls cost $46. One baseball costs one dollar more than two ping-pong balls. Find the cost of one baseball and the cost of one ping-pong ball.

1 baseball cost $4

1 ping pong cost $1.5

Step-by-step explanation:

let the cost of baseball be b and the cost of ping pong be p

10 baseballs = 10b

4 ping pong = 4p

Adding both gives total $46

10b + 4p = 46 •••••••••(i)

baseball costs 1 dollar more than 2 ping pong

b = 2p + 1 •••••••(ii)

Substitute ii into i

10(2p + 1) + 4p = 46

20p + 10 + 4p = 46

24p = 46-10

24p = 36

p = 36/24

p = $1.5

b = 2p + 1

b = 2(1.5) + 1

b = 3 + 1 = $4

i believe the correct answer is option 4.principalities were small territories that were run by russian rulers.

which statement correctly defines principalities in northern asia in the 1200s? principalities were small territories that were run by russian rulers.
