Question asked:
Which equation can be used to find the total number of balloons purchased ?
Solution:
Let total number of balloons purchased = [tex]x[/tex]
70% of the number of balloons purchased = 210
[tex]\frac{70}{100} \times x=210\\ \\ \frac{7x}{10} =210\\ \\ By\ cross\ multiplication\\ \\ 7x=210\times10\\ \\7x=2100\\\\ By\ dividing\ both\ sides\ by\ 7\\ \\ \frac{7x}{7} =\frac{2100}{7} \\ \\ x=300[/tex]
Therefore, total number balloons purchased was 300.
