In a sweet shop you can buy packets of mints for 20p each and bars of chocolate for 30p each. the total cost of m packets for mints and c bars of chocolate is given by the formula t=20m +30c

use this formula to calculate the cost if:

m=2 and c=1
m=8 and c=0

The first equation answer would be 70, whilst the second equation's answer is 160. I think this would be the correct

20(2) + 30(1) = 70.

20 (8) + 30(0) = 160.

Step-by-step explanation:

Basically, you would do 20(2) + 30(1) for one of the equations and 20(8) + 30(0) for the other equation. Those equations would give you the answer.

a. -0.3 > -0.33
