Andy buys x cakes. betty buys 4 times as many cakes as andy. colin buys 3 more cakes than andy. each cake costs 65p. the total cost of the cakes is £52.65. how many cakes did each person buy?

Each cake cost £ 13.00

Step-by-step explanation:

We were given that, each cake costs or £

Andy buys cakes.

Andy's cost is

£

Betty buys 4 times as many cakes as  Andy.

Betty's cost is

£

£

Colin buys 3 more cakes than Andy

Colin's cost is

£

The total cost of the cakes is £ .

This implies that,

We expand to get,

We group like terms to get,

This gives us,

This implies that,

Therefore each cake cost £ 13.00

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)

600,000,000,000, or 6e14
