Answer:

Estimate = $34.50

Actual charge $33.47

Step-by-step explanation:

To estimate, we round the numbers

9.7 gallons rounds to 10 gallons

10 gallons * 3.45 per gallon =34.50

This is an overestimation

The actual charge

9.7* 3.45 =33.465

We round to the nearest cent

33.47

Karo-lina-s [1.5K]
To solve for the homeowner's insurance payment for house built in Area B, we simply multiply the cost of the house with the insurance coverage rate in its decimal equivalent. From the given problem,
                               annual insurance payment = ($65,900)(0.0054)
                                           = $355.86

Which number-line model represents the sum of 1.25+(-0.75)?
SIZIF [17.4K]

Solution:

<u>A few tips...</u>

  • Tip-1: If "+" and "-" are multiplied, it gives a result of "-".
  • Tip-2: If "-" and "-" are multiplied, it gives a result of "+".
  • Tip-3: If "+" and "+" are multiplied, it gives a result of "-".

<u>Changing the sign of the given equation.</u>

  • 1.25 + (-0.75)
  • => 1.25 - 0.75                                        [Sign changes according to tip-1.]

This could only mean that the arrow would go to <u>1.25 units forward.</u> Then a second arrow will be drawn to go <u>0.75 units back.</u>

The graph that matches with the above info is Option C.

Debbie found a suitcase that was originally 129 but now is on sale for 30% off. If sales tax is 8.75%, what is her final cost?
Marizza181 [45]

Step-by-step explanation:

To find the answer we first multiply 129 by 0.7 since the price descresed 30 percent. each percent is equal to 0.01.

129 * 0.7 = 90.3

Then we multiply 90.3 by 1.0875 since that is the sales tax

90.3 * 1.0875 = 98.2

so the cost is 98.2
