Step-by-step explanation:
Her mom had rachel when she was 26 and since rachel isnt 26 and her moms past thw age of 26 the first rwo multiples of 26 are the answers whic is 26 and 52.
Sure. So the hundreds digit is after the tens digit which is 3, so therefore it's 4. The millions digit is 7 places to the left, so it's 7. Ten thousands digits are 5 places to the left, so it's 9. The hundred thousands is 6 to the left, therefore 8. Finally, the thousands is 4 places to the left, so it's 0. Hope this helped!
Answer:
10.5 denarii
Step-by-step explanation:
Step 1: Initially Doubled his money in Lucca and spent 12 denarii
Let's assume the initial money he had before he did anything with it is x,
meaning if he doubled it in Lucca he would have (2×x)=2x, he then spent 12 denarii meaning he was left with (2x-12) denarii.
Step 2: In Florence he doubled what was left on leaving Lucca and spent 12
This is expressed as 2(2x-12)-12=4x-24-12=4x-36
(4x-36) denarii is what remained after he left Florence to Pisa
Step 3: In Pisa he doubled what was left on leaving Florence and spent 12 denarii
This is expressed as 2(4x-36)-12=8x-72-12=8x-84
Step 4: After getting back home in Pisa he was left with nothing
This is expressed as; 8x-84=0, 8x=84
solving for x by dividing both sides of the equation by 8
8x/8=84/8
x=10.5 denarii
Lily made $75.36 more than Layla did. If Layla raised her price to $1.00, she would still not make more money than Lily.
Use a proportion to find the number of cupcakes Lily makes in 8 hours. She bakes 7 cupcakes in 10 minutes; we want to know how many she makes in 8(60)=480 (since there are 8 hours and each hour is 60 minutes):
7/10 = x/480
Cross multiply:
7*480 = 10*x
3360 = 10x
Divide both sides by 10:
3360/10 = 10x/10
336 = x
Lily bakes 336 cupcakes.
She sells 2/3 of these; 2/3(336) = 2/3(336/1) = 672/3 = 224 cupcakes sold.
Each cupcake is sold for $1.29; 224(1.29) = 288.96
To find the number of cupcakes Layla makes in 8 hours, we set up a different proportion. We know she bakes 8 cupcakes in 12 minutes; we want to know how many she bakes in 8(60) = 480 minutes:
8/12 = x/480
8*480 = 12*x
3840 = 12x
Divide both sides by 12:
3840/12 = 12x/12
320 = x
She bakes 320 cupcakes. She sells 75% of those; 75% = 75/100 = 0.75:
0.75(320) = 240
Each of those 240 cupcakes sells for $0.89:
0.89(240) = 213.60
This means Lily makes 288.96-213.60 = 75.36 more than Layla.
If Layla raised her price to $1.00, she would make 1(240) = $240; this is still less than Lily.
