Suppose mina and two of her friends go to the movies. write an expression that could be used to find the total cost for them to go to the movies and buy one of each item.

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.
