Question

BETH and Carley are selling candy bars to raise money for new cheer outfits. Beth has sold one less than twice the number of candy bars carely has sold. If they have 188 candy bars in all how many has Beth sold?

Answer 1

beth sold 125 candy bars

Explanation:

BETH sold (B) = 2 x Carley (C) sold -1

B + C = 188

B = 2C -1

C = 188 - (2C - 1) = -2C + 189

3C = 189

C = 63

B = 188 - 63 = 125

check: 125 = 2 x 63 -1
