Answer:
Simple Interest =$5600 (Principal and Interest)
Compound Interest = $5624.32 (Principal and Interest)
Step-by-step explanation:
Using Simple interest, use the formulae, Principal X Rate X Time
= 5000*4%*3
= $600 Interest
Principal plus Interest = $5600
Using compound Interest, use the formulae P(1+r)^n
P means Principal
R means rate
N means number of years
= 500(1+4%)^3
= $5624.32 (Principal with Interest)
3)
7168
divisible by 2 because the last digit is divisible by 2
NOT divisible by 3 because the sum of its digit (22) is not a multiple of 3
divisible by 4 because the last 2 digits (68) are divisible by 4
NOT divisible by 5 because the last digit (8) is neither 0 nor 5
NOT divisible by 6 (to be divisible y 6, it should be divisible by 2 and 3)
divisible by82 because the last 3 digits (168) ae divisible by 8
NOT divisible by 9 because the sum of its digit (22) is not a multiple of 9
NOT divisible by 10 because the last digit (8) is not 0
Having written the rules, you can easily apply them to solve the last 2 exercices.
2-step equation scenario:
Bob wanted to purchase 2 hats and a pack of gum at one store; the pack of gum was $1.50, but the 2 hats did not have a price. Bob went to another store and found only 1 of the exact same hats that he found at the first store, and a the same pack of gum for a total of $30.
Question: what store has the better deal, where the total will be equal to the second store’s prices?
‘h’ = the hats
Here’s the equation:
2h+1.50=30.
Steps:
1.) Subtraction Property of Equality (inverse properties to combine like terms and define ‘h’): 2h=28.5. We subtracted +1.50 to cancel it out and move it to the other side of the = to combine like terms.
2.) Division Property of Equality (inverse property used to isolate ‘h’). 2h/2=28.5/2=14.25. We divided 2 from 2h to cancel it out and get h alone.
Therefore h=14.25.
This means that store 1 has the better deal, since 2(14.25)+1.50=30. So, Bob can have 2 hats and the pack of gum at store 1 for the same price as only 1 hat and a pack of gum at store 2.
