b) $5000
c) $6000
d) $7000

Answer 1

To find Mr. Wong's salary in July, set up an equation based on the given information and solve for S.

Step-by-step explanation:

To find Mr. Wong's salary in July, we can set up an equation based on the given information. Let's assume that his salary in July is S. According to the problem, he spent 72% of his salary in July, which means he saved 100% - 72% = 28% of his salary.

In August, his salary increased, and he spent 79% of his new salary. He spent $1050 more in August than in July. This can be represented as 0.79(S + 1050) = 0.28S + 1050. By solving this equation, we can find the value of S, which represents Mr. Wong's salary in July.
