There are 26 boys and 19 girls,
Take away 7 from 45 to get 2g(# of girls)
45-7=38 38=2g To get to # of girls,find just one g
38/2=19 so 19 girls
45-19=boys 45-19=26 boys

B + g = 45

b = g + 7

b = 26
g = 19

26 + 19 = 45
26 - 19 = 7

The networking organization you joined is throwing a party. You are in charge of buying the chips, which cost $2.50 per bag and
Julli [10]

Answer:

Number of salsa jars you can buy is 8 jars

The number of bags of chips you can buy is 28 bags

Step-by-step explanation:

The question above is incomplete.

In other to complete it, we would have to make some assumptions.

You are in charge of buying the chips, which cost $2.50 per bag and salsa, which costs $4 per jar. The chips & salsa budget you are given totals $60. The inequality 2.5x + 4y less than or equal to 60 represents the possible combinations of chips (x) and salsa (y ) you can buy.

Hence, we solve for x and y

The inequality is given:

2.5x + 4y ≤ 60

2.5x + 4y = 60........ Equation 1

Let us assume that the total number of bags of chips - jar of salsa you can buy is equal to 20.

Hence:

x - y = 20...... Equation 2

x = 20 + y

Substitute 20 + y for x in Equation 1

2.5x + 4y = 60........ Equation 1

2.5(20 + y) + 4y = 60

50 + 2.5y + 4y = 60

Collect like terms

2.5y + 4y = 60 -50

6.5y = 50

y = 50/6.5

y = 7.6923076923

Approximately to the nearest whole number

Number of salsa jars you can buy is 8

From here, we can solve for x based on this assumptions

x - y = 20

x - 8 = 20

x = 20 + 8

x = 28

The number of bags of chips you can buy is 28 bags
