Linda saves $1.55 every day. Tyron saves $3.90 every day. Linda started saving 3 days earlier than Tyron. On which day will Tyron's savings be more than Linda's savings?

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.
