Michael bought 160 hotdogs were eating competition he spends $240 an hour how much did each hotdog cost
geniusboy [140]

Answer:

$1.50

Step-by-step explanation:

1. we know that its $240 per 160 hot dogs

2. make that a ratio - 240:160

3. simplify the ratio so that the amount of hot dogs is at one (so divide both sides by 160)

4. so 240/160 = 1.5 .   160/160 = 1

5. 1.5:1

6. so for every one hotdog, you pay $1.50

Rina wants to ride the bumper cars 1 time and the Ferris wheel 5 times. It costs 1 ticket to ride the bumper cars and 1 ticket t
Lana71 [14]

Answer:

Rina will need 6 tickets.

Explanation:

Rina needs only 1 ticket to ride the ferris wheel once, and 1 ticket to ride the bumper cars once. If she wants to ride the ferris wheel 5 times, then she'll need 5 tickets since 1 x 5 = 5. If she wants to ride the bumper cars only once, she'll only need 1 ticket since 1 x 1 = 1.

Add the answers together, and you get 6 tickets since 5 + 1 = 6.

Hope this helps! :)
