what was your answer?

ah ok, i got u

so were looking for the amount of t-shirts she sold right? since its unknown we can label it x

knowing that she gets 6 dollard for each t-shirt she sells, we can just multiply x by 6

getting us 6x

not quite but very close

considering her profit was 84, that means that we subtract 6x by 30

because she spent 30 dollars

so now that gets us 6x - 30 = 84

do you know how to solve for x?

ok do that and ill check your answer 🙂

yep, good job

any time, tell me if you have any questions about the process

nah lets just do it here

so first we just have to convert 18 kilometers/hour to meters per hour

that means we multiply 18 by 1000

that gets us 18000 meters per hour

but the question is asking for seconds

so how many seconds are in an hour?

hehe yep

so now we just divide 18000 by 3600

exactly

that gets us 5

so we now know that the cyclist travels 5 meters per second

the question is asking us how far he travels in 5 seconds

so if he travels 5 meters per second, we just have to multiply 5 meters by 5 seconds

getting us 25 meters

np, do you have any questions?

ok sweet, good luck on further tests : D
