A, B and C are three similar solids. The surface area of A is 24 cm
The surface area of B is 54 cm
The height of B: the height of C=3:7
The volume of A is 72 cm
C is made of wood with density 0.14 g/cm3
Work out the mass of C.

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
