Lucy's savings account has 35% more money than her sister Edy's. Together, the girls have saved a total of $206.80. How much mon

Ber [7]

X=Lucy´s money
y=Edy´s money
we can suggest this system of equations:
x=y+(35/100)y ⇒x=135y/100
x+y=206.8

solve by substitution method.
(135y/100)+y=206.8
Least common multiple=100
135y+100y=20680
235y=20680
y=20680/235=88

then:
x=135y/100=135(88)/100=118.8

Answer:
Lucy´s money=$118.8
Edy´s money=$88

To check:
Together, the girls have saved a total of $118.8+$88=$206.8
Lucy´s savings account has: $88+(35/100)$88=$118.8, 35% more monty than Edy´s. account. .

There is a jar on the cabinet by the refrigerator. If Keona pours 114 ounces of water into the jar three times to fill it, how m

I am Lyosha [343]

The amount of quarts of water to fill the jar is 10.6875 quarts

To solve this problem effectively, we need to understand the concept of word problems.

<h3>What are word problems in mathematics?</h3>

Word problems in mathematics are questions that require a crucial understanding and application of mathematical principles to solve them effectively.

From the parameters given:

If 114 ounces of water is poured three times to fill the jar

Then, the total amount of ounces that fills the water is:

= 114 ounces × 3

= 342 ounces

From the dimensional analysis of measurements:

1 ounce = 0.03125 quarts

Thus, in quarts, 342 ounces will be:

$\mathbf{=\dfrac{ (342 \ ounces \times 0.03125 \ quarts)}{1 \ ounce}}$

= 10.6875 quarts

Blairs new computer cost 5$ less than twice the cost og her old computer. Her new computer cost 709$. how much did blairs old co

Phantasy [73]

The cost of old computer is $ 357

<em><u>Solution:</u></em>

Let "x" be the cost of old computer

From given,

Cost of new computer = $ 709

Blairs new computer cost 5$ less than twice the cost of her old computer

Therefore,

Cost of new computer = twice the cost of old computer - 5

Cost of new computer = 2x - 5

709 = 2x - 5

2x = 709 + 5

2x = 714

Divide both sides by 2

x = 357

Thus the cost of old computer is $ 357
