Answer:
The last investment (C) has the least interest of $600
The other two investments (A and B) have the <u>same</u> amount of interest of $1800.
Step-by-step explanation:
<u>Simple Interest Formula</u>
I = Prt
where:
- I = interest earned
- P = principal
- r = interest rate (in decimal form)
- t = time (in years)
<u>Investment A</u>
- P = $2000
- r = 10% = 0.1
- t = 9 years
Substitute the given values into the formula and solve for I:
⇒ I = 2000(0.1)(9)
⇒ I = $1800
<u>Investment B</u>
- P = $3000
- r = 3% = 0.03
- t = 20 years
Substitute the given values into the formula and solve for I:
⇒ I = 3000(0.03)(20)
⇒ I = $1800
<u>Investment C</u>
- P = $2000
- r = 10% = 0.1
- t = 3 years
Substitute the given values into the formula and solve for I:
⇒ I = 2000(0.1)(3)
⇒ I = $600
The last investment (C) has the least interest of $600.
The other two investments (A and B) have the <u>same</u> amount of interest of $1800.
Answer:
18 rubber band bracelets
Step-by-step explanation:
1 hour = 4 bracelets
4.5 hours = ?
4.5 hours/× 4 bracelets
_______
1 hour/
4.5×4 bracelets = 18 bracelets
In an hour Jessica makes four bracelets and in 4.5hours she makes how many bracelets ,we don't know , obviously in 4.5hours she would make more so if more less will divide.
so 4.5hours over 1hour times 4 bracelets. so hour will cancel hour and now 4.5 times 4 bracelets is equal to 18 bracelets
