JT has two jobs. He mows yards and washes cars in his neighborhood. Let X represent the amount of weekly earnings for mowing yards, and let Y represent the amount of weekly earnings for washing cars. The mean of X is $60, and the mean of Y is $35. Which answer choice correctly calculates and interprets the mean of the sum, S = X + Y? Mu Subscript s Baseline = 47.5; next week, JT will earn $47.5.
Mu Subscript s Baseline = 47.5; JT can expect to earn $47.5, on average, in a typical week.
Mu Subscript s Baseline = 95; next week, JT will earn $95.
Mu Subscript s Baseline = 95; JT can expect to earn $95, on average, in a typical week.
