Respuesta :
5 jars of jam and 3 packages of bread mix are in gift basket
Solution:
Let "x" be the number of jars of jam
Let "y" the number of packages of bread mix
Cost of 1 jars of jam = $ 6
Cost of 1 package of bead mix = $ 5
There are 8 items in the basket
Therefore,
number of jars of jam + number of packages of bread mix = 8
x + y = 8 ---------- eqn 1
A gift basket that contains jars of jam and packages of bread mix costs $45
Therefore, we frame a equation as:
number of jars of jam x Cost of 1 jars of jam + number of packages of bread mix x Cost of 1 package of bead mix = 45
[tex]x \times 6 + y \times 5 = 45[/tex]
6x + 5y = 45 --------- eqn 2
Let us solve eqn 1 and eqn 2
From eqn 1,
x = 8 - y --------- eqn 3
Substitute eqn 3 in eqn 2
6(8 - y) + 5y = 45
48 - 6y + 5y = 45
y = 48 - 45
y = 3
Substitute y = 3 in eqn 3
x = 8 - 3
x = 5
Thus 5 jars of jam and 3 packages of bread mix are in gift basket
