Answer:
$4.
Step-by-step explanation:
Let us assume that Pete and Teegan each put an amount of $P in a new bank account.
Teegan's account earns 2.75% simple interest and she earned $2.20 in interest after one year.
So, we can write 
⇒ P = $80
Now, this $80 in Pete's account earns 5% simple interest.
Then after one year Pete will earn as interest 
Dollars. (Answer)
J can find the height of the fifth member on this way
S=150
S1=153
S2=150
S3=151
S4=152
S5=?
S= (s1+s2+s3+s4+s5)/5:
5*150= <span>153+150+151+152+S5
S5=5*150-606=750-606=144
Answer is 144 cm</span>
Answer:
12 dimes and 18 nickels
Step-by-step explanation:
Equations given by word problem:
n + d = 30
0.05n + 0.1d= 2.10
How I solved them:
d= 30 - n
0.05n + 0.1(30 - n)= 2.10
0.05n + 3 - 0.1n= 2.10
-0.05n= -.09
Divide both sides by -0.05
n= 18
18 + d = 30
d= 12
Answer:
17
Step-by-step explanation:
30/-10 + -20/-1
= -3+20
= 17
