David's age: x
Joshua: x + 5
Simon: (x+5) + 4 or x + 9

Simon's age + David's age = 15
(x+9) + (x) = 15
2x = 15 - 9
2x/2 = 6/2
x = 3

The ages of the boys:

David: x = 3 years old
Joshua: 3+5 = 8 years old
Simon: 3+9 = 12 years old

Brad buys a pack of 12 bottles of energy drink for £9.25 he then sells all bottles for £1 each. Work out brads percentage profit
docker41 [41]

Brad's profit was 30%

Further explanation:

Profit is the money someone earns on selling a product on more than its actual cost.

The formula for profit is:

Profit= Selling\ price-Purchase\ price

Given

Purchase price of energy drinks = £9.25

Selling price of one bottle=£1

Selling price of 12 bottles=1*12=£12

Profit= Selling Price - Purchse price

=12-9.25

=£2.75

Brad's profit was £2.75

Now,

Profit percentage= (Profit/Purchase Price)*100

=(2.75/9.25)*100

=0.30*100

=30%

Brad's profit was 30%

Wesley and brian have a total of 87 baseball cards. Wesley have 30 less than twice as many cards as brian. How many baseball car
d1i1m1o1n [39]

Brian has 39 cards and Wesley has 48 cards

Step-by-step explanation:

Let w be the number of cards Wesley has

and

b be the number of cards Brian has

Then

w+b = 87\ \ \ \ Eqn\ 1\\w = 2b-30\ \ \ Eqn\ 2

Putting w = 2b-30 in equation 1

2b-30+b = 87\\3b = 87+30\\3b = 117

Dividing both sides by 3

\frac{3b}{3} = \frac{117}{3}\\b = 39

Putting b=39 in equation 2

w = 2(39)-30\\w = 78-30\\w = 48

Hence,

Brian has 39 cards and Wesley has 48 cards
