the local grocery store sold $1,420 worth of products on monday. they sold $1,235 worth of products on…

Explanation:

Step1: Find the decrease in sales

The sales on Monday is $1,420 and on Tuesday is $1,235. The decrease is $1,420 - $1,235 = $185.

Step2: Calculate the percentage decrease

The formula for percentage decrease is $\frac{\text{Decrease}}{\text{Original Amount}} \times 100%$. Here, the original amount is the sales on Monday ($1,420) and the decrease is $185. So we calculate $\frac{185}{1420} \times 100%$. First, $\frac{185}{1420} \approx 0.1299$. Then, multiplying by 100% gives approximately $0.1299\times100% = 12.99%$, which rounds to 13.0%? Wait, no, wait, let's recalculate. Wait, 1420 - 1235 is 185. Then 185 divided by 1420: 185 ÷ 1420. Let's do this division more accurately. 1420 goes into 185 zero times. Add a decimal point. 1420 goes into 1850 once (1×1420 = 1420). Subtract 1420 from 1850: 430. Bring down a zero: 4300. 1420 goes into 4300 three times (3×1420 = 4260). Subtract 4260 from 4300: 40. Bring down a zero: 400. 1420 goes into 400 zero times. Bring down a zero: 4000. 1420 goes into 4000 two times (2×1420 = 2840). Subtract 2840 from 4000: 1160. So putting it together: 0.1302... So approximately 13.0%? Wait, but let's check the options. Option A is 13.5%, B is 16.7%, C is 13.0%, D is 14.8%. Wait, maybe I made a mistake in subtraction. Wait, 1420 - 1235: 1420 - 1200 is 220, then -35 is 185. Correct. Then 185/1420. Let's compute 185 ÷ 1420. Let's divide numerator and denominator by 5: 37/284. Now 37 ÷ 284. 284 ÷ 37 is about 7.675, so 1/7.675 ≈ 0.1303. So 0.1303×100% = 13.03%, which rounds to 13.0%. So the percentage decrease is approximately 13.0%.

Answer:

C. 13.0%
