Suppose you bought a pizza for $8.00. You also bought a salad but you can not remember how much you paid and you can not find th
e receipt.You know the total amount you spent was $10.00. Which equation would best to answer to find the cost to the salad A:8.00+$=10.00
B:8.00+10.00=$
C:8.00 x $=10.00
D.10.00 x $ = 8.00
with A you get to calculate what is the value of $.
8 + $ = 10 (10 is the total value of your receipt and 8 is the price of pizza) $ = 10 - 8 (we transfer the price of pizza on the other side to the total amount of your receipt and calculate the remaining amount) $ = 2
We see that the remaining amount is 2$, which means the salad cost s2$ :)
to the right of the decimal is tenths > hundredths > thousandths so since at the thousands place the following number is 0 you round down so the answer is 0
