On a hot summer day, Sunny bought 18 ice creams for her team members. Some were \$7 each, and the others were \$10 each. If she paid \$165 in total, how many \$7 ice creams did she buy?

1. number of cheaper ice creams --- x
number of more expensive ones ---- 18-x

solve for x

7x + 10(18-x) = 165

( I know things are getting expensive, but \$10 ice creams ???)
