1a. The new height of the tomato plant is 23cm.
To find this, we need to find what 15% of 20 is and then add it to the 20. To find 15% of 20, we multiply.
15% * 20 = 3
Now we add that to 20 to get the final answer.
20 + 3 = 23
1b. The new tomato plant grew 30%.
In order to find this, we need to use the percent change formula. The formula is below for you.
(New - Old)/Old * 100 = %Change
(312 - 240)/240 * 100 = %Change
72/240 * 100 = %Change
.3 * 100 = %Change
30% = %Change
0.04(30h) is the part of the expression that represents the amount of tax she must pay. This part shows that 0.04 (4%) is the tax rate, 30 is the amount of money needed to pay per hour (h). Taxes are a percentage of the actual price added on to the actual price, so that means that 30h is the actual price, 30 dollars an hour, and 0.04(30h0 are the taxes she has to pay.
