 25/115. This is because the answer is 0.217. All the other proportions are 0.2. If you rounded 25/115, however, the answer would be 0.2. I may be wrong. I can't tell if one option is 17/85 or 12/85. If it says 12/85 then that's the one that doesn't match the other proportions. To find the decimal answer (you can compare all in the end) I usually just divide the denominator by the numerator. :)

David requires at least $300 to hold his birthday party. If David can save $63 a month, how many months will he need to save to
Darya [45]

Answer:

a. 63x \geq 300

b. x \geq 4.76 or x\geq 5

c. For David to achieve three hundred dollars, he would have to save approximately 5 months

Step-by-step explanation:

A. David requires three hundred dollars, this is his goal, indicating the three hundred must be alone. For the inequality sign, the statement says that he "requires at least $300", meaning that he would have to maintain three hundred dollars or his amount could go greater than $300. Therefore, the inequality sign should be "≥" or "greater than or equal to". We also know that David can save 63 dollars per month, meaning that there should be a variable next to 63 so we could replace "x" with any number to solve our inequality. This should leave us with the following inequality :

63x ≥ 300

B. To solve the inequality, we need to get x alone, to do so, divide 63 by both sides,

\frac{63x}{63} \geq \frac{300}{63}

x \geq  4.76

To make it easier, we can round "4.76" to 5.

x \geq 5

C. Already shown in the answer spot

FinnZ [79.3K]
You can round 790 to 800, and 9 to 10. So then it become 800/10, or 80. Your answer would be around 80. Hope I helped!
