The formula is
I=prt
I interest earned 90
P amount invested?
R interest rate 0.04
T time 6/12
Solve the formula for p
P=I÷rt
P=90÷(0.04×(6÷12))
P=4,500 ....answer
60+55+x+20 = 180
x + 135 = 180
x = 180 - 135
x = 45
Answer:
A person in a group where 5 people are sharing 3 small bags of snickers
Step-by-step explanation:
Let the number of calories in one bag of snickers =x
Number of calories in 3 small bags of snickers =3x
- If 5 people share 3 small bags of snickers, 1 person's share

Number of calories in 2 small bags of snickers =2x
- If 7 people share 2 small bags of snickers, 1 person's share

We then compare the two.
Let x=1

Therefore, a person in a group where 5 people are sharing 3 small bags of snickers gets more calories.
It is more by 4000 because 8×10 with the third exponent is 8004 times the third exponent is 4000 important item +4000 equals 8000 so it's 4000
