well...
15 x 20 = 300
300+85 = 385
you can get 20 watches for $385
x= number of boys in the club because it is unknown.
x + 7= the number total number of girls in the club.
Answer:
0.15x + 0.20y = 1.80
Step-by-step explanation:
Here, we are interested in writing an equation for the total cost of the apples and bananas
before we write , kindly understand that 100p = £1
So the cost of apple which is 15p will be 15/100 =£ 0.15
The cost of bananas which is 20p will be 20/100 = £0.2
Thus, the total cost of the apples bought will be number of apples bought * price of apple bought = 0.15 * x = £0.15x
The cost of bananas = number of bananas bought * price of bananas = 0.2 * y = £0.2y
So the total cost of the apples and bananas will be;
0.15x + 0.20y = 1.80
30(x) - 65 = 565, X represents the amount of paychecks he has to cash in and the -65 is the money he has to pay back first.
