Hopefully you are able to clearly see the steps I have taken toward solving this problem in the attachment. In case you have trouble understanding what a reciprocal is, the reciprocal of a number is simply the number flipped. So, if you are given 1/2 and asked what the reciprocal is, it would be 2/1, or just 2. That being said, if you are given a whole number, simply remember that a whole number is ALWAYS equal to itself over one. So, in this case, the "sum of a number and its reciprocal" would be n +
1/n
Answer: 7
Step by Step explanation:
Given:
Saving amount = $900
Cost of Laptop = $600
Cost of food = $60 every 2 weeks
Let x be the number of times Sara can withdraw money for food. The inequality would be:
60x + 600 <u><</u> 900
60x + 600 <u><</u> 900
<u> - 600 -600</u>
60x <u><</u> 300
<u>÷ 60 ÷60</u>
x <u>< </u>5
Sara can withdraw money 5 times or less for food.
6+7=13 is the another way to write ...
hope it is helpful.Thankyou!!!!
