Tom saves $750 a year. Bill saves $60 a month. How much more does Tom save a year than Bill?

wlad13 [49]

Answer:

B) 30

Step-by-step explanation:

Bill saves 60 dollars a month so first you have to find out how much he saves in a year

To find that you multiply 60 by 12 since there are 12 months in a year

60*12 = 720

Tom saves 750 in a year so you have to subtract 750 by 720 to know how much more tom saves

750 - 720 = 30

Mrs. Jones buys two toys for her son. The probability that the first toy is defective is 1/3, and the probability that the secon

sergeinik [125]

Answer:

Probability= $\frac{1}{15}$

Step-by-step explanation:

As it is given that

Probability of toy A is defective is =P(A) = $\frac{1}{3}$

Probability of toy b is defective if A is defective = P (B)= $\frac{1}{5}$

WE have to find the P(A n B)

By the law of Probability

P(A n B) = P (A).P(B)

putting the values given to us

P(AnB)= $\frac{1}{3}$ * $\frac{1}{5}$

Probability= $\frac{1}{15}$

Mike and Kim invest $18,000 in equipment to print yearbooks for schools. Each yearbook costs $5 to print and sells for $30. How

vampirchik [111]

This is a simple equation since they get 30$ and it costs 5$ that means they make 25$ each yearbook. Then you divide 18,000 by 25 and get 720

They have to sell 720 yearbooks :) hope this helped
