Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{1190 \: dollars}}}}}$

Step-by-step explanation:

Cost of 4 TVs = $ 680

Finding the cost of 1 TV

$\sf{ \frac{680}{4} } = 170 \: dollars$

Finding the cost of 7 TVs

Since, the cost of 7 TVs is more than that of 1 TV. So, the cost of 1 TV is multiplied by 7

$\sf{i.e \: 170 \times 7 = 1190 \: dollars}$

Hope I helped!

Best regards! :D

Answer:

We find cost per one from all cost per number of sales = 680/4 = $170 per one.

Then we calculate 7 TVs cost by cost per one × number of sales = 170×7 = $1190
