costs $199.95. remy makes $40.50 each week babysitting. how many total
weeks will he need to babysit to save up enough money for the video

Explanation:

Question 8

Step1: Calculate Option A

Calculate \(0.204\div0.034\). We can do this by multiplying numerator and denominator by 1000 to eliminate decimals: \(\frac{204}{34} = 6\).

Step2: Calculate Option B

Calculate \(0.204\div0.34\). Multiply numerator and denominator by 1000: \(\frac{204}{340}=0.6\).

Step3: Calculate Option C

Calculate \(2.04\div0.034\). Multiply numerator and denominator by 1000: \(\frac{2040}{34} = 60\).

Step4: Calculate Option D

Calculate \(2.04\div0.34\). Multiply numerator and denominator by 100: \(\frac{204}{34}=6\).

The tide rises and falls twice a day, and each time it rises 53.478 feet and falls 53.478 feet. So for one day, the total rise and fall is \(2\times(53.478 + 53.478)\) or simply \(4\times53.478\) (since rise and fall each is 53.478, twice a day means 2 rises and 2 falls, total 4 times 53.478).

There are 7 days in a week. So we take the daily total (from part A) and multiply by 7. So the expression is \(7\times4\times53.478\) (or \(7\times2\times(53.478 + 53.478)\)).

Answer:

B. \(0.204\div0.34\)
