Hey there!
To solve this, you can multiply different numbers with 1.49 til you get 10.00 or very close to 10.00.
1.49 x 2 = 2.98 (that's too small)
1.49 x 3 = 4.47 (that's also too small)
1.49 x 4 = 5.96 (again, too small)
1.49 x 5 = 7.45 (close, but still not exactly 10 or close enough)
1.49 x 6 = 8.94 (correct answer)
It wouldn't be 7 because 1.49 x 7 = 10.43 and Jordan will not have enough money.
Final answer:
Jordan can buy 6 pens <-----
Hope this helps you.
Have a great day!
