Nina is selling three types of energy bars at a market stall. She bought 60 Enerbars at 40p per bar and 120 Grainbars at 50p per bar from her normal supplier. She was also given 60 Amazebars as a promotion from a new supplier. Nina sells the bars for £2.60 and manages to sell all the Enerbars and Grainbars but only some Amazebars. She makes a profit of £475. How many bars did she sell?

Step-by-step explanation:

The two stages of photosynthesis: Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions). Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH.

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
