Just the Mountain bike, cause 4% of $2000 is, $80. and $80 for each year for 7 years make $560. now after 7 years your bank account has $2560. Therefore, you can buy a mountain bike, and have $60 left over, if there is no tax included. But if there is tax, your going to be still short by $115.(calculated according to florida's tax, that is 7%.) Anyways if the tax is over 2% you cant get that bike.
Repost your question. There is clearly a typo on the right side.
Answer:
a= k/4+9b
Step-by-step explanation:
hope this helps, if not let me know!
Let x be the number multiplied by 7.
We get 7x.
At least 30 means GREATER THAN OR EQUAL TO 30 or ⩾ 30.
Put it all together now.
7x ⩾ 30
Divide both sides by 7.
x ⩾ 30/7
Done!
Part A: 0.7(x)
Part B: 8.96/0.7 ---> (You can solve this by yourself)
For getting the answer, you can assume the regular price of the book is x. Then, the sale price would be x-0.3x, which is 0.7x
For part B, the price is 0.7 of the original. Dividing the number by 0.7 gets you the original price
