mylen [45]

Given:

Latasha spends $3.35

Helen spends 4 times as much as Latasha.

Dee spends $7.50 more then Helen.

To find:

The amount Dee spends.

Solution:

It is given that, Latasha spends $3.35.

Helen spends 4 times as much as Latasha.

So, Helen spends = 4 × $3.35

                              = $13.40

Dee spends $7.50 more then Helen.

Dee spends = $13.40+$7.50

                    = $20.90

Therefore, dee spends $20.90.

Bus A leaves the station every 30 mins bus b leaves the station every 20 mins at 10 am both buses leave the station together wor
denis-greek [22]

Answer: 11am

Step-by-step explanation:

To solve this, we have to calculate the lowest common multiple of 20 and 30. This will be:

20 = 20, 40, 60, 80, 100

30 = 30, 60, 90, 120, 150.

Here, the lowest common multiple is 60.

Therefore, we add 60 minutes to 10am. This will be:

= 10am + 1 hour

= 11 am

The next time that both buses leave at the same time would be 11am

Kassie recorded the favorite sport of students at her school. She surveyed 800 students. How many more students chose Baseball t
lisov135 [29]

Answer:

40 more kids chose baseball over basketball.

Step-by-step explanation:

The best way to go about this is to use benchmark percentages.

For baseball, 25% of 800 people chose that, so we can do 800/4 to get 200, so 200 students chose baseball

For basketball, we could do 800/5 but that isn't mental math, so we can do 10% of 800 is 80 and 80*2=160. So 40 more kids chose baseball over basketball.
