Answer 1

`\rm \longrightarrow \:Cost \: \: of \: \: 1 \: \: pizzas \: = (Cost \: \: of \: \: 3 \: \: pizzas )/(Total \: \: pizzas )`

`\rm \longrightarrow \:Cost \: \: of \: \: 1 \: \: pizzas \: = (22.50 )/(3 ) \\`

`\rm \longrightarrow \:Cost \: \: of \: \: 1 \: \: pizzas \: = \cancel(22.50 )/(3 ) \: \: ^(7.5) \\`

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

Hence, the cost of 1 pizza is $7.5
