Answer:
S1548.
Step-by-step explanation:
1-7% =- 0.017 and 5.3% - 0.053.
Kevin : After 1 year he has 43,000 * 0.017 = S731.
Greg: After 1 year he has 43,000 * 0.053 = S2279
Difference = 2279 - 731 = S1548.
Most of those are correct but the ones that are not are, (15+8 divided by 4-6) as division comes first. 6x3-8 as multiplication comes before subtraction. And 2/3+4x2, multiplication comes before addition. So change those couple up and you got it.
C - 7.6 = -4
c = -4 + 7.6
c = 3.6
