Last year the vending machine sold drinks for $1.25. This year the price is $1.50. What is the percent of markup?

The percent of markup is 20%

Step-by-step explanation:

Selling price of the drink = $1.50

Cost of the drink last year = $1.25

Percent of markup = (selling price - cost) (100)/cost

Percent of markup = (1.50 - 1.25)(100) /1.25

= 0.25(100) /1.25

= 25/1.25

= 20%

The percent of markup is 20%

85, 88, 91, 94, 97

Step-by-step explanation:

83, 84, 85, 86, 87

83 × 3 = 249

79 + 85 = 164

249 - 164 = 85

84 × 3 = 252

252 - 164 = 88

85 × 3 = 255

255 - 164 = 91

86 × 3 = 258

258 - 164 = 94

87 × 3 = 261

261 - 164 = 97
