1,2,3,6 are the correct answers.
F(x) = -1.50x + 40.....basically, this is saying that Gloria has 40 bucks in her lunch account and each meal costs her 1.50.
By changing the -1.50 to -2.75 means she is paying more for her meals...the cost of a meal went up from 1.50 to 2.75.
To avoid multiplying the two numbers and then finding the cube root, find the cube root of each number first. the cube root of 27 is 3x3x3, so you can take out the three to outside of the sqrt, to get 3 cube root 18. eighteen does not have a cube root, so that's all you have to do. the answer would be 3 (cube root) 18.

loan= 21450-16450= $5000
apr = .029
.029/12 =.0024
.0024(5000)=12.08
.0024+1=1.0024
1.0024^(5*12)= 1.15
1/1.15= .86
1-.86 = .14
60/ .14= $294.85$
