Answer:
Micah spends $42.21 on paintbrushes.
Paint costs $21.64 per gallon.
Step-by-step explanation:
The paintbrushes are constant/fixed price, the number of gallons of paint are variable, the costs rises linearly with each gallon.
150 - 42.21 = 107.79
The fixed costs for paintbrushes are subtracted from his budget. He then has $107.79 left for paint
107.79 / 21.64 = 4.98105360444
Wich is, it's a pity, slightly less then 5 gallons.
he could buz 4.98 gallons. or, if it has to be a whole number, which I guess it has to be, just 4 gallons and has some money left.
For clarification, < is less than, > is greater than, and then there is =.
A. So you have to take the percent of each number first.
50% of 20 = 0.5 x 20 = 10
40% of 30 = 0.4 x 30 = 12
Then put in the appropriate sign.
10 < 12
B. 75% of 12 = 0.75 x 12 = 9
30% of 20 = 0.3 x 20 = 6
9 > 6
Answer:
300 square feet
Step-by-step explanation:
I times everything together
10×6×5=300
18 / x = 20 / 100
20x = 1800
x = 90
The museum had 90 paintings in April.
Hope this helps!! :)
