Answer: 160
Step-by-step explanation:
Based on the information given in the question, let the total reviews left for the product be represented by x.
Therefore, 65% of x = 104
65% × x = 104
0.65 × x = 104
0.65x = 104
x = 104/0.65
x = 160
Therefore, 160 reviews were left for the product.
The number of weeks required to have enough money in account to buy computer is 12
<em><u>Solution:</u></em>
Given that Maya has $210 in a savings account for a new computer the computer cost $537.15 including sales tax
At the end of each week she deposits $27 into the account
<em><u>To find: number of weeks required to have enough money in the account for the computer</u></em>
Total cost of computer = $ 537.15
Amount in savings account = $ 210
Let "a" be the number of weeks required to have enough money in account to buy computer
Each week she deposits $27 into the account
<em><u>So we can we frame a equation as:</u></em>
total cost of computer = Amount in savings account + (number of weeks x 27)


Thus number of weeks required is 12 approximately
