Ответ:
he should have 348 cars and 173 trucks.
Step-by-step explanation:
Let x represent the number of cars that he should have.
Let y represent the number of trucks that he should have.
He has room on his lot for 521 vehicles. It means that
x + y = 521- - - - -- - - - -1
Ramon has 175 more more cars than trucks. It means that
x = y + 175
Substituting x = y + 175 into equation 1, it becomes
y + 175 + y = 521
2y = 521 - 175 = 346
y = 346/2
y = 173
x = y + 175 = 173 + 175
x = 348
Ответ:
£352.80
Step-by-step explanation:
Divide the total number of catalogues by the per hours and hours.
15 per hour x 8 hours= 90 catalogues
360 catalogues ÷ 90 catalogues = 4 students.
Divide the total number of leaflets by the per hours and hours.
80 per hour x 8 hours= 640 leaflets
1440 leaflets ÷ 640 leaflets = 3 students
4 students + 3 students=7 students.
7 students x £51.30 per day = £352.80
The wage will be £352.80
