Kevin spends $11.25 on lunch every week during the school year. If there are 35.5 weeks during the school year, how much does Kevin spend the entire school year?Remember to round to the nearest penny.

Answers

First, you multiply. You get $399.375. when you round it to the nearest penny, look behind the decimal, see if it's going down to 0, or going higher than 5, then round. the overall answer is going to be..............$399 and 40 cents.

Lunch per week times weeks total
11.25×35.5=399.375
rounded to the nearest penny is the same as the hundredths place which is $399.38 since the next decimal place is 5 or more

5/2=d−2/4

What does d=?

Answers

Use GCF to find the denominator, then solve by adding 4/8 to the other side and simplify.

Answer:

d = 3

Step-by-step explanation:

$(5)/(2)=d-(2)/(4)\qquad\left/(2)/(4)=(2:2)/(4:2)=(1)/(2)\right/\n\n(5)/(2)=d-(1)/(2)\qquad\text{add}\ (1)/(2)\ \text{to both sides}\n\n(5)/(2)+(1)/(2)=d-(1)/(2)+(1)/(2)\n\n(5+1)/(2)=d\n\n(6)/(2)=d\to d=3$

what does 35% off and she bought 124.60 worth of items what would the final bill total be applying the discount of 35%

Answers

so percent means parts out of 100
35% means 35/100=3.5/10=0.35/1=0.35

35% off means find 35% and subtract that
so if she bought 124.60 and subtracted 35%
so then we do
124.6 times 0.35=how much off=43.61
so subtract
124.6-43.61=80.99
another hack is 124.60=100% and 100%-35%=65% so just find 65% of 124.6

answer is end cost=$80.99

mrs.johnson gave a sum of money to her son and daughter in the ratio 5:6. her daughter received $2,400.how much did mrs.johnson give away in all?

Answers

if the daughter got 2,400, then the son got 2,400 * $(5)/(6)$ (we divide what she got into six parts and give him 5 of such parts: this is

2,400 * $(5)/(6)$ = 400*5=2000

and together they got 2000+2400=4400
