On Saturday, Mark sold 2 7/8 gallons of lemonade.

Trava [24]

Answer:

Regan sold $\mathbf{\frac{23}{12}}$ gallons of lemonade

Step-by-step explanation:

Operations with Fractions

Mark sold $2\frac{7}{8}$ gallons of lemonade.

Regan sold $\frac{2}{3}$ as much lemonade as Mark

We can find the portion of lemonade Regan sold by multiplying both fractions. But first, we must convert to improper fraction:

$2\frac{7}{8}=2+\frac{7}{8}=\frac{23}{8}$

Now we multiply:

$\frac{23}{8}\cdot \frac{2}{3}=\frac{46}{24}=\frac{23}{12}$

Regan sold $\mathbf{\frac{23}{12}}$ gallons of lemonade

Yuri purchased 8 trees to have planted at his house. The store charged a delivery fee of $5 per tree.

cestrela7 [59]

Answer:

$16.

Step-by-step explanation:

Let t represent the cost of each tree.

We have been given that Yuri purchased 8 trees to have planted at his house. So the cost of 8 trees will be 8t.

We are also told that the store charged a delivery fee of $5 per tree. So the delivery charges of 8 trees will be $8\times \$5=\$40$

The total cost of purchasing 8 trees will be $8t+40$ .

Since the total cost of the trees including the delivery was $168, so we can get an equation as:

$8t+40=168$

$8t+40-40=168-40$

$8t=128$

Upon dividing both sides of our given equation by 8, we will get:

$\frac{8t}{8}=\frac{128}{8}$

$t=16$

Therefore, the cost of each tree is $16.

If you pay $400 down, plus $80 for the next 12 months, that means you're paying (80*12)+400 which is equal to $1360. You're saving $100 by paying the entire total up front.
