A pasta meal costs $8.95 at a local restaurant the cost to make a copycat version of the pasta meal at home is only $4.75 comple
coldgirl [10]

The absolute and relative cost difference in the restaurant and copycat meal are :

  • Copycat meal is $4.20 less than restaurant meal

  • Restaurant meal cost 1.88 times as much as copycat meal

  • Copycat meal is 53% of the cost of restaurant meal

Cost of restaurant meal = $8.95

Cost of copycat version = $4.75

1.)

Difference in cost of meal for both version :

Cost of restaurant meal - Cost of copycat version

($8.95 - $4.75) = $4.20.

The copycat meal is $4.20 less than the restaurant meal

2.)

Cost of restaurant meal ÷ Cost of copycat version

($8.95 ÷ $4.75) = 1.884 = 1.88(2 decimal places)

The restaurant meal cost 1.88 times as much as the copycat meal

3.)

Percentage = (8.95 - 4.75) × 100% = 53.07% = 53%(nearest whole number)

The copycat meal is 53% of the cost of restaurant meal

Therefore, the relative and absolute cost difference are $4.20, 1.88 times and 53%

5. Solve for each inverse.<br> a. If y = 4x - 10, solve for x.
GREYUIT [131]

Answer:

x = \frac{y+10}{4}

Step-by-step explanation:

Given

y = 4x - 10 ( add 10 to both sides )

y + 10 = 4x ( divide both sides by 4 )

\frac{y+10}{4} = x
