Elena walked 20 minutes more than Lin. Jada walked twice as long as Elena. Jada walked for 90 minutes. The equation 2(x + 20) = 90 describes this situation. Match each amount in the story with the expression that represents it

ANSWER BELOW

Step-by-step explanation:

2(X+20)=90

X+20= 90/2

X+20=45

X= -20+45

x=25

^ Lin walks 25 minutes, representing "x".

in the expression (x+20)= The amount Elena walks cause she walks 20 more minutes than Lin.

Therefore Elena walks for (25+20)=45 minutes . (i subsituted  25 for x)

this part -> (x+20) = represents the amount elena walks.

Jada walks 2 times as much as elena= therefore

2(25+20)=90 minutes

the answer is 62

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
