Answer: (1, 8)
Step-by-step explanation:
<u>Substitute y = 3x + 5 into the equation 2x + 3y = 26:</u>
2x + 3(3x + 5) = 26
2x + 9x + 15 = 26
11x = 26 - 15
11x = 11
x = 1
<u>Substitute the value of x into the equation y = 3x + 5:</u>
y = 3(1) + 5 = 3 + 5 = 8
First they have to decide on a pair of pants and they have 8 different choices. For each of those choices they have a choice of 5 different shirts, so that gives them 8 times 5 = 40 different pant/shirt combinations. For each those 40 possibilities, they have 3 different ties they could select, so altogether they have 40 times 3 = 120 different outfits.
