Step-by-step explanation:
Answer:
They made 4 forks and 6 spoons last April.
Step-by-step explanation:
Let forks they made in april be x and spoons be y.
To make 1 fork we need $2
To make 1 spoon we need $1
They sell 1 fork for $6 and 1 spoon for the same amount So,
now,
Turning it into two equations :-
(x = number of forks and y = number of spoons)
2x + 1y = 14
6x + 6y = 60
Now,
2x + y = 14
y = 14 - 2x
Now,
6x + 6y = 60
or, 6x + 6(14-2x) = 60
or, 6x + 84 - 12x = 60
or, -6x = -24
so, x = 4
Now,
y = 14 - 2x
or, y = 14 - 2×4
or, y = 14-8
so, y = 6
