(p+s)*3
(6.50+4.00)*3= 31.5 dollars
1) so if they spent p and s for each person then you need to times it by 3 bc there were 3 people
eg: if popcorn was 1 dollar and a drink was 2 dollars then 1 +2 dollars= 3 and thats how much one person spent but because there are three ppl, we times by 3 to get 9 dollrs use the same method for questions number 1
2) and q2 is the same kinda strategy as i explained so, 6.50+4.00= 10.5 and bc there are 3 ppl then times by 3= 31.50 dollars
make sure to add a zero at the end bc we are talking about money
Hope this helps!! x
