I do not understand what you are saying.
june=6 months, 6*8.75=52.5
250-52.5 = $197.5?
106 because you need to find smallest 3 digit multiple of 7, then add 1
I would know this literally happened to me.
divide by 2
(I'm new to this, so get a secon opinion:)
variables on one side, constaints on other side,
divide by 7
(I think, I'm only in 7th grade and I'm new to this,so I'm not as smart as CPhill, so try to get a second opinion)
2) 7^1 ones digit=7
7^2 ones digit=9
7^3 ones digit=3
7^4 ones digit=1
7^5 ones digit=7
loop of 4, 2018 is congruent to 2(mod 4)
7^2018 ones digit=9
