Achocolate thickshake costs $2 more than a fruit smoothie. jack pays $27 for 3 chocolate thick shakes and 4 fruit smoothies. how much do a chocolate thickshake and fruit smoothie cost each?
write in a simultaneous equation

Chocolate thickshakes will cost $5 and fruit smoothies will cost $3. Let's say the cost of chocolate thickshakes are x and the cost of fruit smoothies are y.

3x + 4y = 27

3x + 3y = 24

3(2+s)+4s=27 the answer is $3 for smoothies and $5 for the thick shakes

Step-by-step explanation:

Let say t is for thick shake, s is for smoothies

(2+s)=t

Jake pays $27 for 3 thick shakes and 4 smoothies

Then you plug in the information

3t+4s=27

Since we have what thick shakes equals 2+s

3(2+s)+4s=27

then simplify

6+3s+4s=27 Combine like terms

6+7s=27 Do the inverse operation -6 on both sides

7s=21 The divide by 7 to get s by itself

3=s is for the smoothies

Then plug back in s to find the vaule of the thick shakes

2+3=t

5=thick shake

b) 36
