HELPP:
Xavier went to a coffee shop and bought four cups of mocha and three cups of regular coffee for his friends. He spent $15.69. Each cup of mocha costs $1 more than one
cup of regular coffee. How much does one cup of mocha cost?

Respuesta :

Answer:

$2.67

Step-by-step explanation:

Let the price of a cup of regular coffee be $x. Therefore, the price of a cup of mocha would be $(x+1).

Total price = (3 x $x ) + (4 x $(x+1) ) = $(7x + 4)

7x + 4 = 15.69

7x = 11.69

x = 1.67

Price of one cup of mocha = $1.67 + 1 = $2.67
