The Cunningham family went to a dinner at Pasta Palace. Mr Cunningham ordered a meal for &7.50; Mrs. C ordered a meal for $6
SIZIF [17.4K]

The total bill for the Cunningham family was $29.26.

Step-by-step explanation:

Step 1; First we total up the cost of the food alone. Mr. Cunningham spent $7.50, Mrs. Cunningham spent $6.25, the 2 children spent $4.99 each which equals $9.98 for both. So the total of the food alone was $23.73.

Step 2; The sales tax rate was 7.25% of the $23.73. So we multiply 0.0725 (7.25%) with the $23.73 which equals $1.72. So the total bill was for $23.73 + $1.72 which equals $25.45.

Step 3; The Cunningham family left a 15% tip. This was 15% of the toal bill which was $25.45. So we multiply 0.15 (15%) with $25.45 which equals $3.81. So the total bill was food cost + service tax + tips which is $23.73 + $1.72 + $3.81 = $29.26

Please help me. I can’t figure out how to put this in the calculator
spayn [35]

Remove the decimal and put the number over 1000 or the next highest mark(10,100,1000,10000,etc depending on how many figures are in the number)

226/1000

Then divide the two by the Greatest Common Factor. In this case, it will be 2.

113/500

You cannot divide this any further because 113 is a Prime number, and 500 is not divisible by 113.

Which linear equation represents a proportional relationship? A) y = x + 2 B) y = 3x + 0.2 C) y = −0.3x D) y = −3x + 4
posledela

Answer:

answer is c

Step-by-step explanation:y =

−0.3x

The given equations are in slope-intercept form, y = mx + b, where b represents the y-intercept.

Proportional relationships must pass through the origin. Therefore, the y-intercept for the equation must be 0. The y-intercept for y = −0.3x is 0.
