A large company increased its sales from last year to this year by 34%.
AlexFokin [52]

Given:

The last year sales = $288,000,000

Company increased its sales from last year to this year by 34%.

To find:

The this year's sales to the nearest million dollars.

Solution:

We have,

The last year sales = $288 million

The company increased its sales from last year to this year by 34%. So,

This year's sales =288+288\times \dfrac{34}{100}

                            =288+97.92

                            =385.92

                            \approx 386

Therefore, this year's sales were 386 million dollars or $386,000,000.

A bowl holds 3/10 cup of oil when it is 2/5 full. Which statement best describes the quotient of 3/10 divided by 2/5?
muminat
If 3/10 cup is 2/5 full, then the bowl holds:

(3/10) / (2/5)

(3/10)/(2/5) = 3/10 * 5/2 = 15/20 = 3/4

The bowl holds 3/4 of a cup

I’m stumped, can anyone please help me understand this
rodikova [14]

Answer:

<em><u>B. Store T sells apples at the lowest rate</u></em>

Step-by-step explanation:

Store R sells apples at $1.20 <u>per pound.</u>

Store S sells <u>4 pounds</u> of apples at $5.00.

Store T sells <u>3 pounds</u> of apples at $3.48.

To find the answer, <u>you have to find the unit price</u> for both Store S and Store T.

For Store S: 4 pounds = $5. <u>Divide the cost by the pounds</u>. This will give us <u>$1.25 per pound.</u>

For Store T: 3 pounds = $3.48. Same thing as Store S, d<u>ivide the cost by the number of pounds</u>. This will give us <u>1.16 per pound</u>.

Now, we know the unit prices for each store. It's time to answer the question.

A. Store R sells apples at the lowest rate.

This is <em><u>incorrect</u></em> because the store that sells the apples at the lowest rate is Store T.

B. Store T sells the apples at the lowest rate.

This answer is <em><u>correct</u></em>, but I'll also take a look at the other two

C. Store S charges a lower rate for apples than Store T.

Again, this is <em><u>incorrect</u></em> because Store T sells apples at the lowest rate.

D. Store T charges the same rate for apples as Store R.

<em><u>Nope</u></em>, Store T sells the apples at a lower rate than Store R.

This means your answer will be <u>B. Store T sells apples at the lowest rate</u>.
