Answer:
3(2.25+3.25+4.50+7.50)
Step-by-step explanation:
On this question we are using the distributive property, so if they are having three friends, you need to multiply the cost of each item by three. When we simplify this expression we get (3*2.25) + (3*3.25) + (3*4.50) + (3*7.50).
Then we find the answer to each part of the problem
3* 2.25=6.75
3*3.25=9.75
3*4.50=13.50
3*7.50=22.50
Then add: 6.75+9.75+13.50+22.50=$52.50.
