Emery earns money mowing his neighbors' lawns. He charges $1.25 per square yard for each lawn he mows. His neighbors, the Flores
aleksandr82 [10.1K]

Answer: 4.2 yards

Step-by-step explanation:

Let x = length of the Flores' lawn in yards.

Then, Area of lawn = 4x  sq. yard [Area of rectangle = width x length , here width = 4 yds (given)]

Charge per square yard = $1.25

Charge for Flores lawn = 1.25 × (Area of lawn)

= 1.25 (4x)

= 5x

As per given,

5x=21\\\\\Rightarrow\ x=\dfrac{21}{5}\\\\\Rightarrow\ x=4.2

Hence, the length of the Flores's lawn = 4.2 yards

A deli sells a sandwich spread for 6.4per pound. How much do you need to pay for 24 ounces of spread?
Dafna1 [17]

Answer:

You have to pay 9.6.

Step-by-step explanation:

In order to find the answer, first you have to consider that 1 pound is equal to 16 ounces and with that information, you can use a rule of three to find the pounds that 24 ounces represent:

1 pound → 16 ounces

    x       ← 24 ounces

=(24*1)/16=1.5

Now that you know, that 24 ounces are equal to 1.5 pounds you can multiply the price per pound for the number of pounds to find the amount that you need to pay:

6.4*1.5=9.6

According to this, the answer is that you have to pay 9.6.
