Answer:
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
Answer:
$100
Step-by-step explanation:
Given data
Principal = 500
Interest= 5%
Time = 4years
Applying the simple interest expression
SI= PRT/100
substitute
SI= 500*5*4/100
SI= 10000/100
SI= 100
Hence the interest after 4 years is $100
37.8 x 7 = 264.6
