To find: the part of typing that rita can do in 2 hours.

Answer to Problem 1P
work done in 2 hours is 23 and work done in x hours is x3.
Explanation of Solution
Given:
Rita take 3 hour to type a report.
Concept used:
Rate of the work:
Ratio of work to the time interval with changes in time rate of work will change.
work rate=work donetime.
work rate×time=workdone.
Calculation:
If it take her 3 hours to type a report, she get 13 done per hour so her work rate is 13.
Therefore: table to find the work done:
Work rate ×Time=work done | ||
13 | 2 | 23 |
13 | x | x3 |
Hence, the work done in 2 hours is 23 and work done in x hours is x3.

- A craftsman of string instruments has received a new order to craft violins and guitars. The craftsman haslimited resources (wood, string, varnish) and time available to create the instruments. Each type of instrument(violin and guitar) requires specific amounts of these resources as well as a certain amount of time to complete.The craftsman wants to find the optimal number of violins and guitars to create in order to maximize the profitfrom selling them, while respecting the resource and time constraints (all instruments will be sold).The profit from selling each violin is 6,000 NOK, and the profit from selling each guitar is 3,000 NOK.Each violin requires 4 kg of wood, 0.3 l of varnish, and 2 m of string, and takes 3 days to craft. For eachguitar, the craftsman needs 5 kg of wood, 0.1 l of varnish, and 6 m of string, and it takes 2 days to make it.The craftsman’s workshop is stocked with 60 kg of wood, 2.5 l of varnish, and 65 m of string. The order needsto be completed in 30…arrow_forwardC Clever | Portal x ALEKS - Marisa Haskins - Le Marisa Haskins - Essay Temp x Earth and Space 2 Desmos | Graphing Calculator x cwww-awy.aleks.com/alekscgi/x/Isl.exe/10_u-IgNslkr7j8P3JH-IQ2_KWXW3dyps2nJxZ_kvzXfsB26H8ZG13mFzq9lmGAYN JJOEyt0CsUr4AMXmcIVNqw-dNsEi_PzyC7v ◇ Exponents and Exponential Functions Finding the final amount in a word problem on compound interest 0/5 Ma John deposited $4000 into an account with 4.6% interest, compounded annually.
