Answer:
$48.60
Step-by-step explanation:
4 7/5 is a funny way to express a fraction... but anway..... if this is correct, then the answer is as follows:
5/6 kg ------> cost $7.50
1 kg ----> costs $7.50 ÷ 5/6 kg = $9
4 7/5 kg ------> costs $9 x (4 7/5) = $9 x (27/5) = $48.60
It's 7.4 because the 3 doesn't round the 4 up.
The first part is 8 x 40=320
8 x 7=56
320+56 and i am not sure what you have going on on the other half
