Step 1: Write the amount of savings in equation
Linda's savings: s=1.55d
Tyron's savings: m=3.90d
Step 2: Add on the extra days to Linda's savings
Linda's savings s=1.55d+3(1.55)
Step 4: Simplify equation
s=1.55d+3(1.55)
s=1.55d+4.66
Step 5: Substitute numbers for d days until Tyron's m savings is greater than Linda's s saving
m=3.90d s=1.55(2)+4.66
m=3.90(2) s=3.10+4.66
m=7.80 s=7.76
On Tyron's second day he will have more money in his savings than Linda does.
