Lisa has $7.80 to spend on some tomatoes and a loaf of bread. Tomatoes

Sunny_sXe [5.5K]

Answer:

Lisa can buy 5 pounds of tomatoes.

Step-by-step explanation:

Given that Lisa has $ 7.80 to spend on some tomatoes and a loaf of bread, and tomatoes cost $ 1.20 per pound, and a loaf of bread costs $ 1.80, to determine how many pounds of tomatoes she can buy, the following calculation must be performed:

1.20X + 1.80 = 7.80

1.20X = 7.80 - 1.80

X = 6 / 1.20

X = 5

So Lisa can buy 5 pounds of tomatoes.

maksim [4K]

Answer:

The probability that they sit next to each other is 50%.

Step-by-step explanation:

Consider the provided information.

It is given that there are four seats within the row are first come, first served during boarding.

There are 4 seats and 2 customers (Karen and Georgia)

The total number of ways in which Karen and Georgia can sit is: $^4C_2$

Now if they will sit together, then consider Karen and Georgia as a single unit.

Thus, the number of ways in which they can sit together is: $^3C_1$

The required probability is:

$P=\frac{^3C_1}{^4C_2} \\\\P=\frac{3}{6}\\\\P=\frac{1}{2}$

Hence, the probability that they sit next to each other is 50%.
