Answer:

jars of jam = 5, packages of bread mix = 3

Step-by-step explanation:

Given:

A gift basket that contains jars of jam and packages of bread mix costs $45.

There are 8 items in the basket.

Jars of jam cost $6 each.

Packages of bread mix cost $5 each.

Question asked:

We have to find the number of jars of jam and the number of packages of bread mix in the gift basket.

Solution:

Let the number of jars of jam = [tex]x[/tex]

As there are total 8 items in the basket:

Then, the number of packages of bread mix = [tex]8-x[/tex]

As given, total cost of gift basket is $45:

Number of jars of jam [tex]\times[/tex] cost of each jar + Number of packages of bread mix [tex]\times[/tex] cost of each packet = $45

[tex]x\times6+(8-x)\times5=45\\6x+40-5x=45\\x+40=45\\[/tex]

Subtracting both sides by 40,

[tex]x+40-40=45-40\\x=5[/tex]

The number of jars of jam = [tex]x[/tex] = 5

Then, the number of packages of bread mix = [tex]8-x[/tex] = 8 - 5 = 3

Therefore, 5 jars of jam and 3 packages of bread mix are there in the  gift basket.

Answer:

5 jams and 3 bread mixes

Step-by-step explanation:

first we can say that

the number of jars is x

number of bread mixes is y

so we can set up our equation

x+y=8

6x+5y=45

so now we can set up substitution

x=8-y

now we can substitute 8-y in for the x's

so

6(8-y)+5y=45

distribute

48-6y+5y=45

simplify

48-y=45

-y=-3

y=3

now plug that in

x+3=8

x=5
