Liz needs to buy soft drinks for 30 people. At the store she finds that she can buy 6 cans for $2.10. She assumes that each person would drink 2 cans each. WHen she checks her wallet she finds that she only has $20. Does she have enough money to buy soft drinks?
No, because she would need to buy 60 cans making it 60*2.10=126/6=$21.
is that right?
Yes. That's correct. :-)
Yes, that is correct. To determine if Liz has enough money to buy soft drinks for 30 people, we need to calculate the total cost of the soft drinks.
Given that Liz can buy 6 cans for $2.10, we can find the cost of one can by dividing the total price by the quantity of cans: $2.10 / 6 = $0.35 per can.
Assuming each person would drink 2 cans, we can multiply the number of people (30) by the number of cans per person (2) to find the total number of cans required: 30 * 2 = 60 cans.
Now, to calculate the total cost of the 60 cans, we multiply the number of cans by the cost per can: 60 * $0.35 = $21.
Since Liz only has $20, she does not have enough money to buy the required amount of soft drinks.
