A$39
b) $2.50
c) Sinea would spend more- $96 while Ren would spend $80
a) \(\frac{8}{12} = \frac{26}{x}\). Cross multiply and then solve for x.
b) \(\frac{10}{20} = \frac{x}{5}\). Cross multiply and solve for x.
c) Sinea:\(\frac{5}{12} = \frac{40}{x}\). And solve for x.
Ren:\(\frac{10}{20} = \frac{40}{y}\) and solve for y.
