Answer:
64 carnations and 16 roses.
Step-by-step explanation:
The events committee buys 80 flowers
The flowers are a combination of carnations and roses.
Each carnation costs $0.50 and each rose costs $2.50
The committee spends a total of $72
<u>Solution:</u>
<u />
Let there be (c) carnations and (r) roses.
So,
c + r = 80 flowers
and $0.50c + $2.50 = $72
This forms a simultaneous equation:
c + r = 80 ... (i)
0.5c + 2.5r = 72 ... (ii)
Multiplying equation (i) by 0.5 and equation (ii) by 1 gives;
0.5c + 0.5r = 40 ... (i)
0.5c + 2.5r = 72 ... (ii)
Subtracting (i) from (ii) gives;
0c + 2r = 32
2r = 32
r = 32 ÷ 2 = 16
Therefore, there are 16 roses
and 80 - 16 = 64 carnations
It is given in the statement that the increase in number of scones is same from Robbie till Charlie.
Let us assume that Robbie buy x scones and every boy buys y more scones than the previous ones.
The number of scones for each of the boy can be written as:
Robbie = x
Cameron = x + y
Louis = x + 2y
Tom = x + 3y
Charlie = x + 4y
Total number of scones = 60
So,
Robbie and Cameron's combined total number of scones is three sevenths of the total of Louis, Tom and Charlie. Mathematically this can be stated as:
Using Solving the two equations simultaneously:
This means, Robbie buys 8 scones,
Cameron buys 8 + 2 = 10 scones,
Louis buys 8 + 4 = 12 scones,
Tom buys 8 + 6 = 14 scones,
and Charlie buys 8 + 8 = 16 scones
