Answer:
Step-by-step explanation:
19) Let no.of cake made by Andy = x
No. of cake made by Shawn = x + 10
x + ( x+10 ) = 86
2x + 10 = 86
2x =86 -10 = 76
x = 76/2 = 38
No.of cakes made by Andy = 38
No. of cakes made by Shawn = 48
21) No.of cards with mark = 679
No.of cards with John = 679 + 123 = 802
22) No.of bundles = 458
No. of newspapers in each bundle = 250
Total no. of newspapers = 458 * 250 = 114500
23) No. of cars in the parking lot = 1291
No. cars left by evening = 138
No. of cars still in the parking lot = 1291 -138 = 1153
