10 - 5 / 10 ^ 2 + 0.4 (4+0.2)

Alexus [3.1K]

PEMDAS

parenthesis, exponents, mult/division, add/subtract

parenthesis: 4+0.2= 4.2

exponents: 10^2= 10×10= 100

new equation: 10-5/100×0.4(4.2)

multiply/divide: 10-(1/20)×.4×4.2

10-(0.05)(0.4)(4.2)

10-0.002×4.2

add/subtract: 10-0.0084 = 9.9916

Two cars got an oil change at the same auto shop. The shop charges customers for each quart of oil plus a flat fee for labor. Th

zvonat [6]

The labor fee is $13.55 and each quart of oil is $2.25

Step-by-step explanation:

Let,

x be the amount of each quart of oil

y be the amount of labor fee

According to given statement;

5x+y=24.80 Eqn 1

7x+y=29.30 Eqn 2

Subtracting Eqn 1 from Eqn 2

$(7x+y)-(5x+y)=29.30-24.80\\7x+y-5x-y=4.50\\2x=4.50$

Dividing both sides by 2

$\frac{2x}{2}=\frac{4.50}{2}\\x=2.25$

Putting x=2.25 in Eqn 1

$5(2.25)+y=24.80\\11.25+y=24.80\\y=24.80-11.25\\y=13.55$

The labor fee is $13.55 and each quart of oil is $2.25
