consider the export or import X=1000-20E+0.2Yf, M=450+10E+0.15Yd, X=M, where X represents export, M represent import, E represents the exchange rate, Yf represents foreign incom, and Yd represents domestic income. the exogenous variable include Yf &Yd and the endogenous variables are X, M and E. set this up as a system of equation, and solve this system by finding the the inverse of the matrix of parameters?​

step-by-step explanation:

with btw u said 100pts but it clearly says

i answerd and just got 10pts

no hate

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
