1.5 * 8/5 = 0.3*8 = 2.4
2.5 * 8/5 = 0.5*8 = 4.0
3x+2=5x-2
2x=4
x=2 i think is the answer im not sure if i got it right im sorry if i did get it wrong
Answer: 360g
120 --> 10
x ---> 30
120*30=10*x
3600= 10*x
x= 3600/10
x= 360
Matthew needs 360g of flour
Total charge at park, T = 2×charge on adults + 4×charge on children .
T =$(2×16 + 4×10)
T = $72
Now, Melissa's father paid $100 .
Amount her father get back is :
A = $( 100 - 72 )
A = $28
Therefore, her father get $28 back.
Hence, this is the required solution.
