Answer 2

$\rm \longrightarrow \:Cost \: \: of \: \: 1 \: \: pizzas \: = \frac{Cost \: \: of \: \: 3 \: \: pizzas }{Total \: \: pizzas }$

$\rm \longrightarrow \:Cost \: \: of \: \: 1 \: \: pizzas \: = \frac{22.50 }{3 }$

$\rm \longrightarrow \:Cost \: \: of \: \: 1 \: \: pizzas \: = \cancel\frac{22.50 }{3 } \: \: ^{7.5}$

$\rm \longrightarrow \:Cost \: \: of \: \: 1 \: \: pizzas \: = \: 7.5$

Hence, the cost of 1 pizza is $7.5
