A grocer wants to mix two kinds of candy. One kind sells for $1.15 per pound, and the other sells for
scZoUnD [109]

Hey there!

This grocer is mixing two kinds of coffee. I always love the smell of coffee!

We will say that x sells for $1.15 per pound and y sells for $2.75 per pound.

Altogether there are 24 pounds of coffee he is selling.

The algebraic equation would be x + y = 24

At $1.30 per pound, he will make 24 * $1.30 = $31.2

So, how many of the x and y kinds of coffee should he use to make the $1.30 per pound mixture which will net him $31.2?

The algebraic equation would be 1.15x + 2.75y = 31.2

We now have two equations :

x+y = 24

1.15x + 2.75y = 31.2

Substituting x= 24 -y in the second equation gives us

1.15(24-y) + 2.75y = 31.2

27.6 - 1.15y + 2.75y = 31.2

27.6 + 1.6y = 31.2

1.6y = 31.2 - 27.6

0.3y= 3.6

y= 2.25

x + y = 24

x + 2.25 = 24

x = 24 -2.25

x = 21.75

If y=2.25, then x= 21.75 as well.

So, he will use 21.75 pounds of the $1.15 per/lb one and another 2.25 pounds of the $2.75per/lb one.

~Done~

Carl puts $1.10 in his penny bank everyday in the moth of July (31 days). His total savings was $55 at the end of June. What is
docker41 [41]

Answer:

C) About $85

Step-by-step explanation:

Please consider the complete question.

Carl puts $1.10 in his penny bank every day in the month of July (31 days). His total saving at the end of June is $55.00. What is the best estimate at the end of July?

A) about $25

B) about $115

C) about $85

D) about $66

First of all, we will round $1.10 to nearest whole number and round 31 to nearest tens as:

\$1.10\approx \$1

31\approx 30

So amount saved in 30 days would be 30 times $1.

\text{Savings in 30 days}=\$1\times 30

\text{Savings in 30 days}=\$30

Carl's savings at the end of July would be amount saved in June plus amount saved in July that is \$55+\$30=\$85

Therefore, the estimate for Carl's saving at the end of July is $85 and option C is the correct choice.

What is the Integral of 10^ln x dx?
Serjik [45]

10^{\ln x}=e^{\ln 10^{\ln x}}=e^{\ln x\cdot\ln 10}=(e^{\ln x})^{\ln10}=x^{\ln10}

So we have

\displaystyle\int10^{\ln x}\,\mathrm dx=\int x^{\ln10}\,\mathrm dx}=\dfrac{x^{1+\ln10}}{1+\ln10}+C

which, as the above manipulation showed, is equivalent to

\dfrac{x10^{\ln x}}{1+\ln10}+C
