Answer:
[tex]5 \ apples = 85.00[/tex]
[tex]Adonis = 144.67[/tex]
Step-by-step explanation:
Solving (a):
[tex]3\ apples = 51.00[/tex]
Required
The cost of 5
Divide through by 3, to get the cost of 1
[tex]1\ apple = 17.00[/tex]
Multiply through by 5, to get the cost of 5
[tex]5 * 1\ apple = 17.00*5[/tex]
[tex]5 \ apples = 85.00[/tex]
Solving (b):
[tex]Adonis : Lexus = 2 : 3[/tex]
[tex]Lexus= 217[/tex]
Required
Find Adonis' final score
Substitute 217 for Lexus
[tex]Adonis : 217 = 2 : 3[/tex]
Express as fraction
[tex]\frac{Adonis}{217} = \frac{2}{3}[/tex]
[tex]Adonis = \frac{2}{3} * 217[/tex]
[tex]Adonis = \frac{2 * 217}{3}[/tex]
[tex]Adonis = \frac{434}{3}[/tex]
[tex]Adonis = 144.67[/tex]
