The Dakotas rented a minivan for their family vacation. When they returned

Ivahew [28]

Answer:

4 additional days.

Step-by-step explanation:

So the total charge is $575.

It costs $355 for 1 week of use of the van.

1 week is 7 days.

It costs $55 for each extra day of use of the van.

575=55d+355

d is for the unknown extra amount of days.

subtract 355 from both sides

220=55d

divide by 55 on both sides

4=d

So, the Dakotas used the van for 4 additional days. So in total the used the van for 4+7 days.

4+7=11 total days.

But the answer to the question is 4 days, because it specifically ask for additional days.

Richard’s store sells pineapples and grapefruits. Pineapples originally cost $5.15 apiece, and grapefruits originally cost $2.25

sveta [45]

Answer:

c. The price of grapefruits experienced a reduction 6.01 percentage points greater than the price of pineapples.

Step-by-step explanation:

The original price of Pineapples=$5.15

New price of Pineapples=$3.88

Find change in price of Pineapples

Change in price=original price- new price

$=5.15-3.88=1.27$

The price of Pineapple was reduced by $1.27

% reduction in price

(reduction value/original value) × 100

$=\frac{1.27}{5.15} *100=24.66$

=24.66%

The original price of grape fruits=$2.25

New price of grape fruits=$1.56

Change in price of grape fruit

Change in price= original price -new price

$=2.25-1.56=0.69$

% reduction in price of grape fruits

(reduction value/original value)×100

$=\frac{0.69}{2.25} *100=30.67$

=30.67%

Answers

The fruit that has its price reduced by a greater percentage is grape fruit

How many percentage points greater = 30.67%-24.66% = 6.01 points

Alexxx [7]

Answer:

Step-by-step explanation:

its in slope intercept form, or y=mx+b where b is the y intercept, i.e. how far down the line hits the y axis. m would be the slope but we dont need to worry about that for now. since b is the y intercept, -8 would mean 8 units down
