$\$$dollar sign 

Hint #11 / 3

To find the number of subscribers for this month, let’s take the number of subscribers from last month $\blue{200}$start color #6495ed, 200, end color #6495ed, add the new subscribers $\green{40}$start color #28ae7b, 40, end color #28ae7b, and subtract the people who cancelled $\red{10}$start color #df0030, 10, end color #df0030.

Hint #22 / 3

The number of subscribers this month is $\blue{200}+\green{40}-\red{10}=\purple{230}$start color #6495ed, 200, end color #6495ed, plus, start color #28ae7b, 40, end color #28ae7b, minus, start color #df0030, 10, end color #df0030, equals, start color #9d38bd, 230, end color #9d38bd.

Hint #33 / 3

Each subscriber pays $\green{\$5}$start color #28ae7b, dollar sign, 5, end color #28ae7b so the revenue for this month is $\purple{230} \times \green{\$5} = \$1150$start color #9d38bd, 230, end color #9d38bd, times, start color #28ae7b, dollar sign, 5, end color #28ae7b, equals, dollar sign, 1150.
