Answer 2

Mrs. clark spends $89.85 on science kits that cost $5 each plus $4.85 tax on the total bill. How many kits did she buy?

Answer:

Mrs. Clark bought 17 science kits

Solution:

Given that Mrs. clark spends $89.85 on science kits that cost $5 each plus $4.85 tax on the total bill

To find: number of kits she bought

Cost of one kit = $ 5

Tax amount = $ 4.85

Total amount spend including tax = $ 89.85

Lets first get rid of the tax in the total amount

Amount without tax = Total amount spend including tax - Tax amount

Thus amount without tax = $ 89.85 - $ 4.85 = $ 85

Since we know that each kit costs $5, we would divide 85 by 5 to see find how many kits she bought

`\begin{array}{l}{\text { number of kits bought }=\frac{\text { amount spent }}{\text { cost of one kit }}} \\\\ {\text { number of kits bought }=(85)/(5)=17}\end{array}`

Thus Mrs. clark has bought 17 science kits
