Let x be the number of $5 items and y the

Mathematics

Answer:

Answer is 60.

Step-by-step explanation:

Two equations, two unknowns.

As you said, let x be the number of $5 items and y the number of $25 items.

First equation is based on VALUE (second sentence):

5x + 25y = 1950

Second equation is based on NUMBER (third sentence):

x + y = 150

Now solve. Easy way is rearrange the second equation (x = 150 - y) and sub into the first:

5(150 - y) + 25y = 1950

750 - 5y + 25y = 1950

20y = 1200

y = 60

Since y represented the number of items sold at $25, 60 is the number of items.

Answer:

Cost of 1 rose bush = x = $5

Cost of 1 geraniums = y = $2

Step-by-step explanation:

DeShawn and Mike each improved their yards by planting rose bushes and geraniums. They bought their supplies from the same store.

Let us represent:

Cost of 1 rose bush = x

Cost of 1 geraniums = y

DeShawn spent $13 on 1 rose bush and 4 geraniums.

x + 4y = 13..... Equation 1

x = 13 - 4y

Mike spent $56 on 10 rose bushes and 3 geraniums.

10x + 3y = 56....... Equation 2

We substitute 13 - 4y for x in Equation 2

10(13 - 4y) + 3y = 56

130 - 40y + 3y = 56

Collect like terms

- 40y + 3y = 56 - 130

-37y = -74

y = -74/37

y = $2

Solving for x

x = 13 - 4y

x = _13 - 4 × $2

x = $13 - $8

x = $5

Therefore,

Cost of 1 rose bush = x = $5

Cost of 1 geraniums = y = $2
