You work for 6.5 hours at a rate of $11.50 / hour.

you buy dinner that costs $12, and give a 20% tip.

how much money are you left with?

Step-by-step explanation:

step 1

Find the total amount of money worked

Multiply 6.5 hours by the rate $11.50 / hour.

step 2

Find the total cost of the dinner

Remember that

so

the cost of the dinner plus the tip is equal to

step 3

Find the amount of money left

Subtract the total cost from the total amount of money

so

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!
