3) Mrs. Noah’s bill, before tax, is $50. The sales tax rate is 3%. Mrs. Noah decides to leave a 2% tip for the gate keeper based on the pre-tax amount. How much will the total bill be, includingtax and tip?

$52.50

Step-by-step explanation:

Start with       $50

Add 2% Tip:  $1         (50 x 0.02)

Add 3% Tax: $1.5      (50 x 0.03)

Total:            $52.50

52.50

Step-by-step explanation:

Because 3+2=5% and 5% of 50 dollars is 2.50 so 50+2.50 =52.50 dollars he is paying in total

your answer would be 10x - 1

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
