The gardeners should buy 54 white hydrangeas and 88 pink hydrangeas altogether.
Step-by-step explanation:
Let,
Number of white hydrangeas = x
Number of pink hydrangeas = y
According to given statement;
In first bed
x+y = 40 Eqn 1
In second bed
2 times the number of white hydrangeas and 3 times the number of pink hydrangeas as in the first bed.
2x+3y=102 Eqn 2
Multiplying Eqn 1 by 2
Subtracting Eqn 3 from Eqn 2
Putting y=22 in Eqn 1
Number of white hydrangeas altogether = x+2x = 3x = 3(18) = 54
Number of pink hydrangeas altogether = y+3y = 4y = 4(22) = 88
The gardeners should buy 54 white hydrangeas and 88 pink hydrangeas altogether.
