Question

Brian can type 50 words per minute. He needs to finish typing his 700-word essay and already has 375 words typed. Write and solve an equation to determine the number of minutes (m) that it will take Brian to finish writing his essay. (Round your answer to the nearest tenth)

Answer 1

so the equation would be 50m + 375 = 700

i got this because we know that for every minute, m, he types 50 words. since he already has 375, we can just add that onto the 50m. those two combined, 50m + 375, must equal 700, so that is what the equation equals.

to solve for this, we first subtract 375 on both sides to get 50m = 325, then divide both sides by 50, and get that m = 6.5
