Eequation 3(x-1.25) = 11.25 his work is shown below.
3(x-1.25) = 11.25
3x-3.75 = 11.25
3x-3.75 +3.75 = 11.25 +3.75
3x = 15
3x 3 = 45.3
x= 135
what mistake did tobin make?
tobin did not distribute the 3 correctly
tobin should have subtracted 3.75 from each side
tobin should have divided by 3

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?
