Each hotdog cost $1.50 and sodas cost $.50. At the end of the day you made a total of $78.50.You sold a total of 87 hot dogs and

Maru [420]

Answer:

35 hotdogs and 52 sodas were sold.

Step-by-step explanation:

Create equations to represent the problem.

let "d" be the number of hotdogs sold

let "a" be the number of sodas sold

1.5d + 0.5a = 78.50 Equation for money made

d + a = 87 Equation for items sold

Rearrange d + a = 87 to isolate one of the variables.

a = 87 - d

Substitute a for 87-d into the other equation. Isolate using reverse operations.

1.5d + 0.5a = 78.50

1.5d + 0.5(87 - d) = 78.50 Distribute over brackets by multiplying

1.5d + 43.5 - 0.5d = 78.50 Collect like terms

43.5 + d = 78.50 1.5d - 0.5d is 1d. You don't need to write "1".

43.5 + d - 43.5 = 78.50 - 43.5 Isolate d, subtract 43.5 from both sides

d = 35 Number of hotdogs sold

Substitute d for 35 in the simpler equation

d + a = 87

35 + a = 87 Subtract 35 form both sides to isolate "a".

a = 87 - 35

a = 52 Number of sodas sold

Therefore 35 hotdogs and 52 sodas were sold.

An office building casts a shadow that is 55 m long. At the exact same time, a 5 m tree casts a shadow that is 1.1 m long. Use s

kotegsom [21]

The ratio of the triangle is 55/1.1, which is 50/1.

This means that the building is 50/1 = x/5

x = 250

The office building is 250 m tall.

Claire mowed 4 lawns last week. She mowed each lawn in startfraction 7 over 27 endfraction hour. She mowed the same lawns this w

maw [93]

Claire's time to mow all the lawns last week was 1.4 times longer than this week.

Explanation

Claire mowed each lawn in $\frac{7}{27}$ hour last week.

So, the total time taken to mow all 4 lawns last week $=\frac{7}{27}*4=\frac{28}{27}$ hours.

She mowed the same lawns this week and took $\frac{5}{27}$ hour for each.

So, the total time taken to mow all 4 lawns this week $=\frac{5}{27}*4=\frac{20}{27}$ hours.

Now.....

(Total time in last week / Total time in this week) $=\frac{(\frac{28}{27})}{(\frac{20}{27})} = \frac{28}{20}=\frac{7}{5}=1.4$

So, Claire's time to mow all the lawns last week was 1.4 times longer than this week.
