The College Board discovered a mistake! All of their tests administered in 2017 were scored 50 points lower than they should have been. Assuming they have a vector called SAT.2017 that includes all test scores, how would they add 50 points to each score in the vector? a) SAT.2017 + 50
b) SAT.2017 <- add(50)
c) sum(SAT,50)
d) sum(SAT+50)

Acoffee shop orders at most $3,500 worth of coffee and tea. the shop needs to make a profit of at least $1,900 on the order. the possible combinations of coffee and tea for this order are given by this system of inequalities, where c = pounds of coffee and t = pounds of tea: 6c + 13t ≤ 3,500 3.50c + 4t ≥ 1,900 which graph's shaded region represents the possible combinations of coffee and tea for this order?
