Find rhe x-intercept od the line by letting y=0 ans solving for xx-3y=4

Step-by-step explanation:

for 11,000 she had no tax

32,000 of which she had to pay at a rate of 20%

10% of 32,000 = 3200 which you then multiply by 2

6400 - save this for later

she has 2,600 of which she has to pay 40% tax

260 x 4 = 1040

add 1040 + 6400 together and you get 7440 which is how much she payed
