Question

The first real answer gets brainlest.

Mr. Hammond is the volunteer coordinator for a company that puts on running races. Last year, the company organized 7 short races and 8 long races, which required a total of 804 volunteers. This year, the company organized 11 short races and 5 long races, which required 688 volunteers in total. How many volunteers does each type of race require?

Answer 1

Let the volunteers of

Long race be x

Short race be y

7y + 8x = 804 ... .. (i)

11y + 5x = 688 ... .. (ii)

5(i) - 8(ii)

35y + 40x = 4020

88y + 40x = 5504

On solving the above equations,

y = 28 , x = 76

i.e., volunteers of Long race = x = 76

volunteers of Short race = y = 28
