Ms. gartland bought x number of shirts for the new members of her chorus. the cost for x number of shirts, including $3.99 shipping, was $ 77.49.each shirt cost $12.25.there was no sales tax on this purchase. which equation could be used to find x? a 3.99(x+12.25)=77.49 b 3.99x+12.25=77.49 c 12.25(x+3.99)=77.49 d12.25x+3.99=77.49

She bought 'x' number of shirts.

The price of one shirt = 12.25 dollars.

Then total price of all shirts would be '12.25x' dollars.

Given is the shipping charge = 3.99 dollars.

Given is the total bill = 77.49 dollars.

It says no other tax would be charged on this order, so total bill would be sum of total price of all shirts and shipping charges.

Total Bill = Total price of all shirts + Shipping charges.

77.49 = 12.25x + 3.99

Hence, option D is correct i.e. 12.25x + 3.99 = 77.49

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9
