Juan works mowing lawns and babysitting. He earns $8.70 an hour for mowing and $7.40 an hour for babysitting. How much will he earn for 6 hours of mowing and 1 hour of babysitting?
For mowing lawns he earns 8.70*6 = $<<8.70*6=52.20>>52.20
For babysitting he earns 7.40*1 = $<<7.40*1=7.40>>7.40
In total for 6 hours of mowing and 1 hour of babysitting, Juan will earn 52.20+7.40 = $<<52.20+7.40=59.60>>59.60. Answer: \boxed{59.60}.
Bill sells beaded necklaces. Each large necklace sells for $5.20 and each small necklace sells for $4.20 . How much will he earn from selling 6 large necklaces and 4 small necklaces?
He earns 5.20 * 6 = $<<5.20*6=31.20>>31.20 from selling the large necklaces.
He earns 4.20 * 4 = $<<4.20*4=16.80>>16.80 from selling the small necklaces.
He will earn 31.20 + 16.80 = $<<31.20+16.80=48.00>>48.00 in total. Answer: \boxed{48.00}.
The price of an item has been reduced by $2.29 . The new sale price is $34.22 . What was the original price?
Let's assume the original price was $x.
The sale price is the original price minus the reduction, so we have the equation:
x - 2.29 = 34.22
To isolate x, we add 2.29 to both sides of the equation:
x = 34.22 + 2.29
x = 36.51
Therefore, the original price was $36.51. Answer: \boxed{36.51}.
Raina wants to pour $80.79 grams of salt into a container. So far, she has poured 18.5 grams. How much more salt should Raina pour?
To find out how much more salt Raina should pour, we subtract the amount of salt already poured from the desired total amount:
$80.79 - $18.5 = $62.29
Raina should pour $62.29 more grams of salt. Answer: \boxed{62.29}.
