Party supplies inc. sells metallic ballons for $2 each and helium ballons for 3: 50 per bunch. yesterday the sold 36 more metallic ballons than the number of bunches of helium ballons the total sale for both types of ballons was $281. let b represent the amount of metallic sold

Metallic Balloons = 74

Bunches of Helium Balloons = 38

Step-by-step explanation:

The question basically asks for the number of "metallic balloons" sold and the number of bunches of "helium balloons" sold.

We will do it in our way. Let B be number o metallic balloons and H be number of bunches of Helium balloons.

Since Metallics cost 2 each and Heliums cost 3.5 per bunch and totaled sales is 281, we can write and equation as:

2B + 3.5H = 281

and, since they sold 36 MORE metallic than helium ,we can write an equation as:

B - 36 = H

We can put 2nd equation in 1st one and solve for B first:

B = 74

Now, we find H:

H = B - 36

H = 74 - 36 = 38

H = 38

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
