In a local city, the temperature at noon is -3C The temperature is expected to decrease by 2.5C each hour until the temperature

LiRa [457]

Writing the equation that governs this situation:

-3C - (2.5C/hr)x = -18C

Simplifying, -3 - 2.5x = -18, or 3 + 2.5x = 18

Combining like terms: 2.5x = 18-3 = 15

Then x = 15/2.5 = 6. The temp. will reach -18C after 6 hours.

Ricks sporting good:

100% - 20% = 80% so the basketball is on sale for 80% of the original price so 24.95 x 0.80 = 19.96 ( sale price)

Sports Expert:
100% - 25% = 75%
so the basketball is on sale for 75% of the original price 25.80 x 0.75 = 19.35 (sale price)

19.35 is less than 19.96 so the better deal is from Sports Expert
