Select the correct answer from each drop-down menu. a store sells t-shirts for $10 each and jeans for $20 a pair. anna spends $150 on t-shirts and jeans. she buys x t-shirts and y pairs of jeans. the equation that represents the situation is . if anna decides to buy only t-shirts and no jeans, she can buy t-shirts with the money she has.

The equation that represents the situation is 10x + 20y =  150.

She can buy 15 T- shirts with the money she has.

Step-by-step explanation:

Here, x represents the number of T-shirts bought and y represents the number of pair of jeans,

Part 1 : Since, each shirts costs $10 and each pair of jeans costs $ 20,

Thus, her total sending = 10x+20y

According to the question,

10x + 20y =  150 (1)

Which is the required equation that represents the situation.

Part 2 :

If Anna decides to buy only T-shirts and no jeans

Then y = 0,

From equation (1),

10x = 150

⇒ x = 15

Thus, she can buy 15 T- shirts with the money she has.

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
