Chris and Dave and Ed share £720 between them. Chris receives £90 more than Dave. The ratio of Chris's share to Dave's share is
jolli1 [7]

Answer:

Ratio of Ed's share :  Dave's share  = 4 : 5

Step-by-step explanation:

Total amount shared =  £720

Let us assume that Dave receives =  £m

So, Chris's share = £90 + m

Also, Chris's share : Dave's Share = 7: 5

⇒\frac{90 + m}{m}  = \frac{7}{5}

Here, solving for m , we get :  5(90 + m) = 7m

or,  450 + 5m = 7m

⇒ 2m = 450, ⇒ m = 225

So, Dave's Share =  m = £225

Chris's share = £90 + m = 225 + 90  = £ 315

Hence, Ed's share = Total - ( sum of Dave's and Chris's share)

= 720 -( 315 + 225) = £180

So, ratio of Ed's share :  Dave's share = £180 : £225

or, Ratio of Ed's share :  Dave's share  = 4: 5

In the first week of​ July, a record 1,040 people went to the local swimming pool. In the second​ week, 105 fewer people went to
lesantik [10]

Answer:

The percentage of people going to the people in week 4 compared to week 1 decreased by 25%.

Step-by-step explanation:

Week 1: 1,040 people

Week 2: 105 fewer people

1040 - 105 = 935 people

Week 3: 135 more people

935 + 135 = 1070 people

Week 4: 290 fewer people

1070 - 290 = 780 people

So, there were 260 fewer people, going to the pool in those 4 weeks compared to week 1.

Now, we must find the percentage change.

x/100 = 780/1040

Cross multiply.

1040x = 78000

Divide both sides by 1040 to leave x by itself on one side.

x = 78000/1040

x = 75%

This means only 75% of the total people from week one were going to the pool in week four. Therefore, there was a 25% decrease in the number of people who went to the pool over these four weeks.
