Part A What is Mikaela's income today? $ 60 Part B Suppose smoothies are measured on the y-axis and sodas are measured on the x-axis. What is the absolute value of the slope of Mikaela's budget constraint today? |1.25 Part C Suppose Mikaela has discovered a new love for coffee and tea and would like to add both to her weekly beverage consumption. Coffee costs $2/cup and tea costs $1.50/cup. Mikaela would like to maximize utility given her income.
