Answer:

5/8

Step-by-step explanation:

28x + 4 can be factorised because 28 is a multiple of 4

so it can become

4(7x+1)

35x + 5 can be also factorised because 35 is a multiple of 5

5(7x+1)

we can now rewrite the expression as

6/4(7x+1) * 5(7x+1)/12

we can “eliminate” the two 7x+1 and simplify 6 with 12

so it remains

1/4 * 5/2 = 5/8

Use the multiplier 1.055

final = original x multiplier^n

where 'n' is the number of years

Sub the values in

final = 700 x 1.055^7

final = 1018.27

Subtract the values:

1018.27 - 700 = 318.27

Thus, he earns more than $275

He earns $43.27 more
