James earned $3 an hour baby-sitting and $4 an hour washing cars. last week he did baby-sitting for 5 hours and car washing for 3 hours. how much more money does he need to buy a game that cost $35?

$8

Step-by-step explanation:

Total amount earned from baby-sitting = 3 × 5 = 15

Total amount earned from washing cars = 4 × 3 = 12

Total amount earned = 15 + 12 = 27

Amount of money needed to buy = 35 - 27 = 8.

He needs $8.

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
