A number composed of two digits divisible by 5 and tens digit is less than unit digit by one
9514 1404 393
Answer:
45
Step-by-step explanation:
Only numbers ending in 5 or 0 are divisible by 5. If the units digit is 0, there can be no tens digit that is 1 less. So, the units digit must be 5 and the tens digit must be 4.
The number is 45.

Greta currently works 45 hours per week and earns a weekly salary of $729. She
will soon be starting a new job where her salary will be increased by 10% and her hours reduced by 10%.
How much more will she be earning per hour at her new job?
Answer:
$7.29 per hour at her new job.
Step-by-step explanation:
Answer:
$3.60
Step-by-step explanation:
Her hourly wage at her old job is 729/45 or $16.20 per hour. If her salary is increased by 10% then her wage weekly is $801.90. If her hours are reduced by 10% then she has to work 40.5 hours per week. This means you have to do 801.90/40.5 to get $19.80 per hour. So according to my math here she will make $3.60 more per hour at her new job. (Double check to make sure I'm correct)

Step-by-step explanation:
t-shirts for $2 and shorts for $4. the total sales were $600. they sold four times more tshirts than shorts how many tshirts and shorts did they sell?
Answer:
T-shirts: 200
Shorts: 50
Step-by-step explanation:
To solve, set up an equation using two variables to represent the number of t-shirts and shorts sold. Let x = t-shirts sold. Let y = shorts sold. 2x + 4y = 600. We know that x will be 4 times greater than y, so we can plug in some guesses that seem reasonable and use the equation to test our theories. My first guess was 50 shorts, which by luck was the correct answer. These problems can be tricky, but setting up an equation can prove to be a great help.

Step-by-step explanation:
Suppose Gil can write a poem in 1 hour, Holly can write a poem in 2 hours, and Ivan can write a poem in 3 hours. Each person spends 12 hours per day writing poems and requires a wage of $10 per hour to do so. If a literary magazine needs one poem, how much will it cost
Answer:
The literary magazine must pay $ 10 if poem is written by Gil, $ 20 if poem is written by Holly and $ 30 if poem is written by Ivan.
Step-by-step explanation:
The wage indicate the amount of money earned in hour for production of poems. If a literary magazine needs just one poem, then the cost will be the wage multiplied by time taken for the creation of the poem. There are three possibilities:
Gil
[tex]C = \left(10\,\frac{USD}{h})\cdot (1\,h)[/tex]
[tex]C = 10\,USD[/tex]
Holly
[tex]C = \left(10\,\frac{USD}{h}\right)\cdot (2\,h)[/tex]
[tex]C = 20\,USD[/tex]
Ivan
[tex]C = \left(10\,\frac{USD}{h}\right)\cdot (3\,h)[/tex]
[tex]C = 30\,USD[/tex]
The literary magazine must pay $ 10 if poem is written by Gil, $ 20 if poem is written by Holly and $ 30 if poem is written by Ivan.
