Answer:
The cost of 1 medium smoothie = $3.38
Step-by-step explanation:
Cost of 1 jumbo smoothie = $4.95
⇒ Cost 2 Jumbo Smoothies = 2 x $4.95 = $9.9
Let us assume the cost of 1 medium smoothie = m
Now, the Cost of 2 jumbo smoothie and 1 medium smoothie + $0.15
= 4 (cost of 1 medium smoothie)
⇒ $9.9 + m + $0.15 = 4 m
or, 10.15 = 4 m - m
or, 3 m = 10.15
⇒ m = 10.15/3 = 3.38
or, m = 3.38
Hence, the cost of 1 medium smoothie = $3.38

In 2010 there were 100 times as many text messages as in 2005.
Answer:
∠ BCE = 80°
Step-by-step explanation:
∠ BCD = ∠ ABC = 35° ( alternate angles are congruent )
∠ DCE and ∠ CEF are same- side interior angles and supplementary, thus
∠ DCE + ∠ CEF = 180° , that is
∠ DCE + 135° = 180° ( subtract 135° from both sides )
∠ DCE = 45°
Thus
∠ BCE = ∠ BCD + ∠ DCE = 35° + 45° = 80°
