You practice the piano for 30 min. each day. Write and solve an equation to find the total time t you spend practicing the piano in a week.

There are 7 days a week, and you spend 30 minutes each day practicing

T = Time spend studying

30 * 7 = T

T = 210 minutes studying!

Lets get all the information we need first.

A week has 7 days, you practice 30 min each day, so in a week you will practice a total time t of 30 min for 7 times, that is:

t = 7day (30 min/day)

t = 210 min

So in a week you will practice a total of 210 minutes.
