Mary Jo spends $1,450 to buy stock in two companies. She pays $15 a share to one of the companies and $20 a
share to the other. If she ends up with a total of 90 shares, how many shares did she buy at $15 a share and how
many did she buy at $20 a share?

Answers

Answer:

she bought 70 shares of the $15 shares

she bought 20 shares of the $20 shares

Step-by-step explanation:

this would be solved using simultaneous equation

let a = $15 shares

b = 20 shares

a + b = 90   equation 1

15a + 20b = 1450  equation 2

Multiply  equation 1  by 15

15a + 15b = 1350  equation 3

subtract  equation 3 from  equation 2

5b = 100

b = 20

substitute for b in  equation 1

20 + a = 90

a = 70

Cars A and B leave the same place and travel in the same direction along a straight road. Car A travels at 60 km/h and car B travels at 72 km/h. After how long will they be at 8km apart?

Answers

Answer:

Car A: 8 minutes

Car B: 6.67 minutes

Step-by-step explanation:

Car A: 60km evrery hour so,

1 km every minute, so he will be in 8km in 8 minutes.

Car B: 72km per hour so,

72/60 = 1.2 = 1.2 km per minute.

8/1.2 = 6.6666666666667 which is about 6.67 to the nearest hundredth.

Answer:

Car A is traveling at 1 km/min (60/60)

Car B is traveling at 1.2 km/min (72/60)

Car B gains .2km on Car A for every minute they drive.

8km/.2 = 40
