The number of 7th graders attending Middlefield Science Academy this year is 130% of last year’s total. If 500 7th graders atten
ded last year, how many attend this year? A tape diagram. There are 130 students who are 7th graders this year out of 100 who were 7th graders last year. There are question mark students this year out of 500 who were 7th graders last year. Which steps should be used to find 130% of 500? Check all that apply. (100)(50) = 500 (100)(5) = 500 (130)(5) = 650 StartFraction 130 Over 100 EndFraction = StartFraction 130 Over 100 EndFraction = StartFraction 650 Over 500 EndFraction There are 650 7th graders this year.
First we need to isolate the variable so we add 15 to both sides which is w/4=43 then we need to multiply by 4 to both sides so its 4w=172 then divide by 4 which is 43 so the answer is w=43
